Question

Find the surface are of a sphere that has a diameter of square root of 29

Answer 1

Hello!

The surface area of a sphere can be found using this equation: SA = 4πr².

The radius is half the diameter. So, half of √29 is √29 / 2, in simple terms.

SA = 4π(√29/2)²

SA = 4π(7.25)

SA = 4(7.25)π

SA = 29π

SA = 91.10618...

Therefore, the surface area of this sphere is 91.11 units².

Without multiplying π, the surface area is 29π units².

If the question asked substitute π for 3.14, the answer is 91.06 units².
