Question

The radius of a circle is 14 feet. What is the area of the circle?

A. 87.92 ft2
B. 153.86 ft2
C. 1,230.44 ft2
D. 615.44 ft2

Answer 1

`\textit{Area of a Circle}\\\\ A=\pi r^2 ~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=14 \end{cases}\implies A=\pi (14)^2\implies \stackrel{ using~\pi =3.14 }{A=615.44}~ft^2`

Answer 2

D

Explanation:

the area (A) of a circle is calculated as

A = πr² ( r is the radius )

here r = 14 and approximating π to 3.14 , then

A = 3.14 × 14² = 3.14 × 196 = 615.44 ft²
