Question

The diameter of a circle is 12 inches. What is the area of the circle. Use 3.14 for the radius​

Answer 1

113.04 Sq. Inches

Explanation:

d = 2r => r = d/2 = 12/2 = 6 inches

A = π·r² = 3.14×36 = 113.04 Sq. Inches

Answer 2

R=6

A=36
`\pi` Or 113.09733552923(113.1 rounded to the nearest tenth)

Explanation:

R=d/2

12/2=6

A=
`D/2^(2)`

12/2=
`6^(2)`

6*6=36
`\pi`

(36*3.14=113.09733552923 if you don’t have pi symbol)

113.09733552923 rounded=113.1
