sphere a has a radius that is three times larger than the radius of sphere b let sa and SB represent the surface areas of sphere a and sphere b

Answer 1

respectively. We can use the formula for the surface area of a sphere, which is 4πr^2, where r is the radius.

Since the radius of sphere a is three times larger than the radius of sphere b, we can let the radius of sphere b be r and the radius of sphere a be 3r.

Therefore, the surface area of sphere a (Sa) is 4π(3r)^2 = 36πr^2.

And the surface area of sphere b (Sb) is 4πr^2.

So, Sa = 36πr^2 and Sb = 4πr^2.
