6. What would be the approximate surface area of a sphere with a radius of 2 in?

Question

*
SA=50 sq in
SA= 60 sq in
SA = 40 sq in

Answer 1

The approximate surface area of a sphere with a radius of 2 inches can be calculated using the formula:

SA = 4πr²

where r is the radius.

Plugging in the values:

SA = 4π(2)²
SA = 4π(4)
SA ≈ 16π

Using an approximate value of π as 3.14:

SA ≈ 16(3.14)
SA ≈ 50.24

So the approximate surface area of the sphere would be 50.24 square inches.
