Sheena wants to measure the volume of a ball that is 24 cm across how should she set up her equation?

Assuming the ball to be completely spherical, its volume can be calculated using: Volume = 4/3 * pi * r^3 Because the measured parameter is the diameter of the ball, we may substitute: r = d/2 into the equation: Volume = 4/3 * pi * d^3 / 8 Using this equation, Sheena can compute the volume to be: V = 4/3 * pi * (24) ^3 / 8 V = 7,238.2 cubic centimeters
