Question

A circle has a diameter of 24 units. What is the area of the circle to the nearest hundredth of a square unit?

A
37.70
B.
75.40
452.39
D.
1809.56

Answer 1

Answer:C (452.39)

Explanation:

1. Area = πr²

Circumfrence = 2πr

diameter = 2r

24/2 = radius = (r)

π(12)²= 144π

π ≈ 3.14

144 * π = 452.39

Answer 2

A circle with a diameter of 24 would have an area of 452.39. 452.39 rounded to the nearest hundred is 452.40.
