The surface area of a spherical lampshade is 57.76 square inches. what is the radius of the lampshade?

We are given area of the spherical lampshade =  57.76 \pi square inches.

We know formula of area of a spherical shape:

Plugging area A= 57.76 π in formula, we get

Dividing both sides by 4π, we get

Taking square root on both sides, we get

r =3.8.

Therefore, the radius of the lampshade is 3.8 inches.

What are you asking ?

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )
