Question

Find the surface area of the figure below.

A. 261.34 ft2

B. 95.03 ft2

C. 23.76 ft2

D. 32.67 ft2

Answer 1

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

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.

Answer 2

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.
