Question

If a circle has a diameter of 24 inches, which expression gives its area in

square inches?
O A. 12.
O B. 242.17
O C. 24. 1
O D. 122.77

Answer 1

D. 12²•π

Explanation:

Area of a circle = πr²

Radius (r) = ½ of diameter = ½*24 = 12 inches

Plug in the value into the area

Area = π * (12)²

Area = π * 12²

Area = 12²•π
