The height of one right circular cylinder is 6 centimeters and its radius is 3 centimeters. The height of a second right circular cylinder is 18 centimeters and its radius is 3 centimeters. The volume of the second cylinder is how many times as large as the volume of the first cylinder?

A. 12

B. 4

C. 3

D. 2

Step-by-step explanation:

Given that the height of one right circular cylinder is 6 centimeters and its radius is 3 centimeters.

Let be the height and radius of the first right circular cylinder respectively.

∴ and

The height of a second right circular cylinder is 18 centimeters and its radius is 3 centimeters.

Let be the height and radius of the second right circular cylinder respectively.

∴ and

The formula for Volume of right circular cylinder is

units

The  Volume of first right circular cylinder is

Substitute the values in the formula we get

units

∴ units

The  Volume of second right circular cylinder is

Substitute the values in the formula we get

units

∴ units

From the volumes we get

∴

17   x 256=4352

sorry if this is wrong, i'm new.

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
