The volume of a cylinder is 54π cubic inches and the height is 6 inches. Find the radius.
Anika [276]

Answer:

The radius of the cylinder is 3 inches.

Step-by-step explanation:

For any given cylinder, the volume can be expressed as:

volume = \pir^{2}h

where r is the radius of its circular surface, and h is its height.

Given that: volume = 54π cubic inches, and the height = 6 inches.

then,

54\pi = \pi x r^{2} x 6

54\pi  = 6\pir^{2}

r^{2} = \frac{54\pi }{6\pi }

   = 9

r = \sqrt{9}

r = 3

The radius of the cylinder is 3 inches.

I need help with this math question(picture included)
sattari [20]

Answer: Your answer should be 12:23

Step-by-step explanation: on the clock the time is 2:25. You simply subtract 2:48 and 2:25. 48-25=23 and the twos cancel out but instead of putting zero you put 12 since your going backwards two on the clock. Hope it helps!!!
