Let V represent the volume of a sphere with radiusr mm. Write an equation for V (in mm) in terms of r. V(r) = mm3 Find the radius of a sphere (in mm) when its diameter is 40 mm. r = mm The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 40 mm? (Round your answer to two decimal places.) mm3/s
