Question

A circle has a diameter of 12 inches. What is the best approximation of its area? Use 3.14 to approximate for π .

A: 18.84 in²
B: 39.14 in²
C:113.04 in²
D:452.16 in²

Answer 1

The answer is C. 113.04in²

12/2=6

A=πr²

A=π6²

A=(3.14)(36) = 113.04in²

Answer 2

C. 113.04 in'2

Step-by-step explanation:

STEP 1:

3.14 x 6'2 ~ 113.04

Step-by-step explanation:

The formula for solving the area of a circle is- 3.14 x r'2

r=radius
