Question

What is the area of a circle with a diameter of 23 centimeters? Use 3.14 for pi. Enter your answer, as a decimal, in the box.

Answer 1

The equation for the area of a circle is A = PI x r^2

R = radius, which is half the diameter = 23/2 = 11.5

Area = 3.14 x 11.5^2

Area = 3.14 x 132.25

Area = 415.265 square cm.
