Question

A clock has a face in the shape of a circle. The distance across the circle is 12 inches. What is the area of the clock face in square inches(sq. in) ?

Answer 1

Area of a circle formula: area = pi x r^2

R is the radius which is half the diameter.

Area of the clock = pi x 6^2

Area = 36 pi. Square inches ( exact area)

Or using 3.14 for pi = 113.04 square inches
