Question

Find the surface area of the figure below.

Answer 1

The answer is b: 95.03 ft^2

Divide 5.5 by 2 to get the radius of 2.75.

Use 4(pi)(r)^2 to get the surface area of the sphere.

Answer 2

Answer:

B. $\displaystyle 95,03\:ft.^2$

Step-by-step explanation:

$\displaystyle 4πr^2 = S.A. \\ \\ 4π[2,75]^2 = 4π[7,5625] = 30,25π ≈ 95,03317777... ≈ 95,03$

* The radius is half the diameter.
