We have been given a sphere with radius 8.6 ft. We are asked to find the surface area of the given sphere.

We know that surface area of a sphere is equal to
$4\pi r^2$ .

$A=4\pi r^2$

Upon substituting
$r=8.6\text{ ft}$ in surface area formula, we will get:

$A=4\pi (8.6\text{ ft})^2$

$A=4\pi \cdot 73.96\text{ ft}^2$

$A=295.84\pi\text{ ft}^2$

$A=929.4087706\text{ ft}^2$

Upon rounding to nearest hundredth, we will get:

$A\approx 929.41\text{ ft}^2$

Therefore, the surface of the given sphere would be approximately
$929.41\text{ ft}^2$ .
