Question

The volume, V, of a cylinder is V =3.14 to second power h, where r is the radius of the cylinder and h is the height. Using rounding to the nearest whole number, which of the following is an estimate of the volume of a cylinder with a radius of 3.75 inches and height of 6.21 inches

Answer 1

Answer:

The formula you have is incorrect. It should be V = π*r2*h.

In order, for you to isolate h, you will need to move π*r2 to the left side. Since π*r2 is multiplied with h, you need to divide both sides of the equation by π*r2 (or multiply by 1/(π*r2); it's the same thing).

V = π*r2*h

[1/(π*r2)]V= π*r2*h[1/(π*r2)]... and now cancel like terms on the right side

V/(π*r2) = h

And you are done.
