Acylindrical rain barrel has a radius of 2 feet and holds a total of 30 cubic feet of water. how tall is the rain barrel? use 3.14 for pi. round your answer to the nearest hundredth.

1.58 feet
2.39 feet
3.57 feet
4.78 feet

2.39 feet

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

where

r is the radius of the base of the cylinder

h is the height of the cylinder

we have

substitute

Solve for h

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the diameter is 16 cm. are you a teacher?
