Find the surface area of the sphere to the nearest square unit. use a calculator.

Surface area of sphere = 12.56 square inches ( nearest 13 (square inches)

Step-by-step explanation:

Given : A sphere with diameter 2 in.

To find : Find the surface area of the sphere to the nearest square unit.

Solution : We have given that a sphere with diameter 2 in.

Surface area of sphere = .

Radius = .

Radius = 1 inches.

Plugging the values of radius  = 1 inches in formula .

Surface area of sphere = .

Surface area of sphere = 12.56 square inches.

Therefore, Surface area of sphere = 12.56 ( nearest 13) (square inches).
