Geometry Formulas

Geometry deals with shapes, sizes, and spatial relationships. The GED Formula Sheet provides essential formulas for calculating area, volume, and understanding geometric relationships.

Area of Shapes

Understanding area is fundamental. The Formula Sheet includes formulas for:

• Square: Area = s² (where s = side length)
• Rectangle: Area = lw (where l = length, w = width)
• Triangle: Area = (1/2) bh (where b = base, h

  **= height)

• Circle: Area = πr² (where r = radius, π ≈ 3.14)

Example: A rectangular garden is 12 feet long and 8 feet wide. What is the area?

Using the formula: Area = lw = 12 feet** 8 feet = 96 square feet.

Volume of 3D Figures

Volume measures the space occupied by a three-dimensional object. Key formulas include:

• Cube: Volume = s³ (where s = side length)
• Cylinder: Volume = πr²h (where r = radius, h = height)

Example: A cylindrical water tank has a radius of 3 feet and a height of 5 feet. What is the volume?

Using the formula: Volume = πr²h = π (3 feet)² 5 feet ≈ 141.37 cubic feet.

Pythagorean Theorem

The Pythagorean Theorem applies to right triangles and relates the lengths of the sides.

The formula: a² + b² = c² (where a and b are the legs, and c is the hypotenuse).

Example: A right triangle has legs of 3 inches and 4 inches. What is the length of the hypotenuse?

Using the formula: 3² + 4² = c² => 9 + 16 = c² => 25 = c² => c = 5 inches.

Algebra Formulas

Algebra involves variables, equations, and relationships between quantities. The GED Formula Sheet provides formulas to help you solve algebraic problems.

Slope-Intercept Form

This form represents a linear equation.

The formula: y = mx + b (where m = slope, b = y-intercept).

Example: Identify the slope and y-intercept of the equation y = 2x + 3.

Slope (m) = 2, y-intercept (b) = 3.

Quadratic Formula

The quadratic formula solves for the roots of a quadratic equation.

The formula: x = (-b ± √(b² – 4ac)) / (2a) for the equation ax² + bx + c = 0.

Example: Solve the equation x² – 5x + 6 = 0 using the quadratic formula.

Here, a = 1, b = -5, c = 6.

Plugging into the formula, we find x = 2 and x = 3.

Simple Interest

Simple interest calculates the interest earned on a principal amount.

The formula: I = Prt (where I = interest, P = principal, r = interest rate, t = time).

Example: You invest $1000 at a simple interest rate of 5% per year for 3 years. How much interest will you earn?

Using the formula: I = $1000 0.05 3 = $150.

Measurement Formulas

The Measurement section of the GED Formula Sheet provides conversion factors and formulas for calculating perimeter and circumference.

Converting Units

Being able to convert units is essential for many problems. The formula sheet offers common conversions, but understanding the process is key.

Example: Convert 60 inches to feet.

Since 1 foot = 12 inches, divide 60 inches by 12 to get 5 feet.

Calculating Perimeter and Circumference

• Perimeter: The total distance around a shape. For a rectangle: Perimeter = 2l + 2w.
• Circumference: The distance around a circle. Circumference = 2πr.

Example: A rectangular room is 15 feet long and 10 feet wide. What is the perimeter?

Perimeter = 2(15 feet) + 2(10 feet) = 30 feet + 20 feet = 50 feet.

Applying Formulas: Practice Problems

Now, let’s solidify your understanding with practice problems.

These examples illustrate how to identify the relevant formula and apply it to solve a GED-style question.

(Problem 1): A circular swimming pool has a diameter of 20 feet. What is the area of the pool?

• Solution: First, find the radius (radius = diameter / 2 = 10 feet).
• Then, use the area of a circle formula: Area = πr² = π * (10 feet)² ≈ 314.16 square feet.

(Problem 2): What is the volume of a rectangular prism that is 4 feet long, 3 feet wide, and 2 feet high?

• Solution: Volume = length width height = 4 feet 3 feet 2 feet = 24 cubic feet.

Understanding the "Why" Behind the Formulas

While memorizing formulas is helpful, truly understanding why they work is crucial. For example, knowing that the area of a rectangle is base times height helps you understand why the area is measured in square units. This deeper understanding allows you to apply the formulas correctly, even when the problems are presented in unfamiliar ways.

Example 1: Area of a Composite Shape

A rectangular room is 15 feet long and 12 feet wide. A square rug covers a portion of the floor. The rug has sides of 6 feet. How much of the floor is not covered by the rug?

• Solution:
  1. Find the area of the room: Area = lw = 15 ft

     **12 ft = 180 ft²

  2. Find the area of the rug: Area = s² = 6 ft** 6 ft = 36 ft²
  3. Subtract the rug’s area from the room’s area: 180 ft² – 36 ft² = 144 ft²
  4. Answer: 144 square feet of the floor is not covered by the rug.

Example 2: Using the Pythagorean Theorem

A 20-foot ladder leans against a wall. The base of the ladder is 5 feet away from the wall. How high up the wall does the ladder reach?

• Solution:
  1. Recognize this as a right triangle problem, using the Pythagorean Theorem: a² + b² = c²
  2. Identify: c = 20 ft (ladder), a = 5 ft (distance from the wall)
  3. Solve for b (height on the wall):
     • 5² + b² = 20²
     • 25 + b² = 400
     • b² = 375
     • b = √375 ≈ 19.36 ft
  4. Answer: The ladder reaches approximately 19.36 feet up the wall.

By practicing these strategies and working through real-world examples, you’ll build confidence and improve your ability to effectively use the GED Formula Sheet on test day.
