1. 10 hr + 39 min = (10 hr x 60 min/1 hr) + 39 min = 600 min + 39 min = 639 min

2. 91 cm/day x 1 in/2.54 cm x 1 day/24 hr = (91 x 1 x 1)/(1 x 2.54 x 24) = 1.49 in/hr

Answer:

Step-by-step explanation:

The formula for the volume of a cylinder is $\pi r^2 h$ , where r is the radius of the base and h is the height of the cylinder.

The answer would be 24pi inches.

You can find this by using the formula for a circumference and plugging in the value of the radius.

C = 2pi*r

C = 2pi * 12

C = 24pi
