Question

question 28 points 2 find the surface area of a spherical ball with a radius of 2 feet. 4π ft² 6π ft² 12π ft² 16π ft²

Explanation:

Step1: Recall 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 \(r = 2\) feet. Substitute \(r = 2\) into \(S=4\pi r^{2}\), we get \(S = 4\pi\times(2)^{2}\).
First, calculate \((2)^{2}=4\). Then \(S = 4\pi\times4\).
Since \(4\times4 = 16\), so \(S=16\pi\) square feet.

Answer:

\(16\pi\ ft^{2}\)
