A cylinder and a cone have the same base and altitude. If the volume of the cone is 30 cubic inches, what is the volume of the cylinder? A. 10 cubic inches
B. 15 cubic inches
C. 30 cubic inches
D. 60 cubic inches
E. 90 cubic inches

The volume of the cylinder is 90 cubic inches. Choice E

Step-by-step explanation:

The Volume of a Cone and a Cylinder

Given a cone of radius r and height h, the volume is calculated as:

If we have a cylinder with the same dimensions, the volume is:

Substituting from the first formula:

The volume of the cylinder is 90 cubic inches. Choice E

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
