The spheres are similar. the surface area of the blue sphere is 7854 square inches. what is the surface area of the red sphere? round your answer to the nearest tenth.

Surface area of red sphere is 1257 square inches.

Step-by-step explanation:

Given : The surface area of the blue sphere is 7854 square inches.

We have to find the  surface area of the red sphere.

Since , radius of red sphere is 10 inches

We know, Surface area of red sphere is

Put r = 10

We have,

Surface area of red sphere is

Using π = 3.14 , we have,

Thus, Surface area of red sphere is 1257 square inches.
