Answer:
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 [tex]4\pi r^2[/tex]
Put r = 10
We have,
Surface area of red sphere is [tex]4\pi (10)^2=400\pi[/tex]
Using π = 3.14 , we have,
Thus, Surface area of red sphere is 1257 square inches.
