Question

find the surface area of this sphere. sphere formulas sa = 4πr² v = 4/3πr³ sa = ?π in²

Explanation:

Step1: Substitute the radius into the formula

Given the formula for the surface area of a sphere \( SA = 4\pi r^{2}\), and \(r = 11\) in.
Substitute \(r = 11\) into the formula: \(SA=4\pi\times(11)^{2}\).

Step2: Calculate the value of \(4\times(11)^{2}\)

First, calculate \(11^{2}=121\).
Then, \(4\times121 = 484\).

Answer:

\(484\)
