Question

Find the radius of sphere ahose surface area is 154cm^2

Answer 1

Hello friend your answer is
Surface area is 4πr²=154
4×22/7×r²=154
r²=154×7/88= 12.25
r=√12.25

Answer 2

♧♧HERE IS YOUR ANSWER♧♧

Let, r be the radius of the sphere.

Then,

surface area of the sphere = 154 cm²

=> 4πr² = 154

=> r² = 154/(4π)

=> r = 3.5

(Aoid the negative value and only take approximate value)

Therefore radius of the sphere is 3.5 cm (approximately).
