The volume of a cylinder is the area of the circular face times the length of the cylinder.

the area of a circular face is
 A=\pi r^2 = \pi\frac{d^2}{4}

hence the volume is
V= \pi r^2 L = \pi \frac{d^2}{4} L

the Length "L" is 36 in
the diameter "d" is 3 in

The radius of a sphere is multiplied by 1/7. What effect does this have on the volume of the sphere?
Cloud [144]

Answer:

The new volume is 1/343 of the old volume or the ratio of the new volume to the old volume is 1 to 343

Step-by-step explanation:

In this question, we are asked to state the effect of multiplying the radius of a sphere by 1/7 on the volume.

Mathematically, the volume of a sphere V can be calculated using the formula

V = 4/3 * π * r^3

Now multiplying the radius by 1/7, the new radius will be r/7

Thus the new volume here will be

V2 = 4/3 * π * (r/7)^3

V2 = 4/3 * π * (r^3)/343

Thus we can conclude that the value of the volume will be decreased by a factor of 343

Meaning the ratio of the old volume to the new volume will be 1 to 343
