Question

find the surface area of this sphere. sphere formulas sa = 4πr² v = $\frac{4}{3}$πr³ sa = ?π in²

Explanation:

Step1: Identify the radius value

$r = 7$ in

Step2: Substitute radius into formula

$SA=4\pi r^{2}=4\pi\times(7)^{2}$

Step3: Calculate the result

$4\pi\times49 = 196\pi$

Answer:

$196$
