Explanation: The best way to understand measurement is by looking at some examples. Take turns and read each example for easy understanding. |
Examples:
A circle has radius of 2 meters. What is the surface area of the circle?
Step 1a
|
|
The surface area of a circle can be found using the formula: \$ A = π * r^2 \$ where A represents the surface area and r is the circle’s radius. |
|
Explanation: Here, we know the formula for the surface area of a circle. |
Step 1b
|
|
Given that the radius of the circle is 2 meters, we can substitute this value into the formula: \$ A = π * (2 "meters")^2 \$ \$A = π * 4 "square meters" \$ \$A ≈ 3.14159 * 4 "square meters"\$ A ≈ 12.56636 square meters Therefore, the surface area of the circle with a radius of 2 meters is approximately 12.57 square meters |
|
Explanation: Here, we substitute the radius in the surface area of a circle. |
