The volume of each shape is 250 cubic inches.
A) Find the height of a cylinder with a radius of 3 inches.
250/3^2/ 3.14 = height of cylinder?

B)Find the radius of the sphere.
Is it just 3 inches?

C) Find the height of a cone with a radius of 3 inches.
I need help with this can someone please check if I'm doing this right?

  • math - ,

    A. V = pi*r^2 * h = 250 in^3
    h =250 / pi*r^2 = 250 / 28.3 = 8.84 In.

    B. V = (4/3)pi*r^3 = 250 In^3
    r^3 = 250 / (4/3)pi = 250 / 4.19 = 59.7
    r = 3.91 In.

    C. V = (1/3)pi*r^2*h = 250 In^3
    Solve for h.
