Acylinder has a radius of 3 feet and a height of 7 feet. which of the following can be used to calculate the volume of a cone that fits exactly inside the cylinder?

The formula is used to find the cone volume.

Step-by-step explanation:

We know that the radius of cylinder is = 3 feet

Height of the cylinder is = 7 feet

Its volume can be found as :

= cubic feet

Now, volume of cone is given as :

This means, the volume of cone is one-third the volume of cylinder.

So, the volume of cone that can fit in the cylinder will be one-third the volume of cylinder.

cubic feet

If we want to check we can say that the volume of cylinder is three times cone.

Therefore, a cone with volume 65.94 cubic feet will fit into a cylinder with volume 192.82.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

the answer is 11.2 (i know i’m late)
