A cone and a cylinder have the same base and height, as shown below. A cone is inside of a cylinder with same base and height. T
lord [1]

Answer:

The volume of the cone = 28 inch³

Step-by-step explanation:

First let's consider the formula for the volume of the shapes

For cylinder

Volume= πr²h

For cone

Volume= 1/3 πr²h

So we'd notice that no much difference except that the volume if a cylinder is divided by two to get that off a cone.

So if the volume of the cylinder is

84π inch

The volume of the cone is 84/3 = 28

The volume of the cone = 28 inch³

The varsity football team consists of seniors and juniors. The number of seniors is 7 less than the number of juniors. There are
harkovskaia [24]

Answer:

There are 18 seniors and 25 juniors.

Step-by-step explanation:

  • Find your equation. For this equation, it comes out to be:

                  x + x + 7= 43   or   2x+7=43

        X represents the amount of seniors.

        The amount of juniors can be represented as x+7

  • Solve the equation. It comes out to be:

        1st - Transfer the 7 to the other side to get the x by itself

                  2x=36

        2nd - Divide 36 by 2 to leave x by itself

                   x=18

  • Answer the question. Because you didn't specify what your were asking for, I imagine it's the number of player from each class.

                   Because x represents the seniors, there are 18 seniors.

                   There are 7 more juniors, add 7 to 18, so there's 25.
