Is it abc or d . i really want to understand this

B

Step-by-step explanation:

The surface area (A) of a sphere is

A = 4πr² ← r is the radius which we require

Given A = 2500π, then

4πr² = 2500π ( divide both sides by 4π )

r² = 625 ( take the square root of both sides )

r = 25

The volume (V) of a sphere is

V = πr³, and

= r³ = × 25³ , thus

= × 15625 ≈ 20833.33.. → B
