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.
1 answer:
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.
