WebJEE Main 2013: If the surface area of a sphere of radius r is increasing uniformly at the rate 8 cm2/s, then the rate of change of its volume is: (A) Web22 jun. 2015 · 1 Answer Truong-Son N. Jun 22, 2015 Using r to represent the radius and t for time, you can write the first rate as: dr dt = 4 mm s or r = r(t) = 4t The formula for a solid sphere's volume is: V = V (r) = 4 3πr3 When you take the derivative of both sides with respect to time... dV dt = 4 3 π(3r2)( dr dt)
