Question

Determine the area of the given figure. circle d=10 ft

Solution

VerifiedStep 1

1 of 2Area of the circle is

$A=\pi r^2=\pi \left(\frac{d}{2}\right)^2$

where $r$ is the radius of the circle and $d$ is the diameter.

Given:

$d=10 \text{ \ ft} \Rightarrow r=\frac{d}{2}=\frac{10}{2}=5 \text{ \ ft}$

So,

$A=\pi r^2=\pi (5)^2=25 \pi \text{ \ ft}^2 =25 \times 3.14 \approx 78.5 \text{ \ ft}^2$
