Find the surface area of a sphere with a radius of [tex]2\sqrt{2}[/tex] feet.

A. 94.5 square feet
B. 100.5 square feet
C. 25.1 square feet
D. 35.5 square feet

Answer :

Answer: 100.5 square feet

Step-by-step explanation:

To find : surface area of sphere with radius of [tex]2\sqrt{2}feet[/tex]

The formula used to calculate surface area of sphere is = [tex]4\times \pi\times r^2[/tex]

where r is the radius of sphere.

Putting the values we get:

surface area of sphere = [tex]4\times 3.14\times (2\sqrt{2}feet)^2=100.5square feet[/tex]

Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet

Answer:

100.5 square ft
