Find the area of a circle whose radius is 12.7 cm
To find the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius.
In this case, the radius is given as 12.7 cm.
Step 1: Plug in the value of the radius into the formula: A = π(12.7)^2
Step 2: Square the radius: A = π(161.29)
Step 3: Multiply π (pi) by the squared radius: A ≈ 3.14159 * 161.29
Step 4: Calculate the result: A ≈ 506.71 square centimeters
Therefore, the area of the circle with a radius of 12.7 cm is approximately 506.71 square centimeters.
Area equals pi * r^2
A = 3.14 * 12.7 * 12.7
A = _____ square centimeters
