Question

If the radius of a circle is $6ft$, what is the area of a circle?

Answer 1

$\approx 113$ square feet
The area of a circle is given by formula:
$\pi r^2$
Where,
$\pi$ has a constant value of $\approx 3.14$
and $r$ denotes the radius.
The radius of the circle is $r=6$ ft
The area $=\pi r^2\approx 3.14\times (6{)}^2$
$\approx 3.14\times \left(36\right)$
$\approx 113.04$ square feet
$\approx 113$ square feet.
