Question

what is the surface area of the 3 - d solid? 37.68 square feet 113.04 square feet 37.68 cubic feet 113.04 cubic feet

Explanation:

Step1: Identify the formula for the surface area of a sphere

The formula for the surface area of a sphere is \(S = 4\pi r^{2}\), where \(r\) is the radius of the sphere.

Step2: Substitute the given radius into the formula

Given \(r = 3\) ft. Substitute \(r = 3\) into \(S=4\pi r^{2}\).

Using \(\pi\approx3.14\), we get \(S\approx36\times3.14 = 113.04\) square feet. Also, note that the unit for surface area is square units, so we can eliminate the options with cubic units (cubic feet).

Answer:

113.04 square feet
