3 answers

The formula for the surface area of a sphere is given by A = 4πr^2, where r is the radius of the sphere.

Substituting the given values, we get A = 4 * 3.14 * (3.6 ft)^2.

Plugging the value of the radius, we have A = 4 * 3.14 * 12.96 ft^2.

Calculating the expression, we find A = 162.3744 ft^2.

Rounded to the nearest hundredth, the surface area of the sphere is 162.37 ft^2. Answer: \boxed{162.37}.
