V = 1649.34

Step-by-step explanation:

The formula for solving the volume of a right cylinder is V = pi r^2h where r = radius and h = height.

We know that radius is half the diameter so r = 5 because the diameter is 10 ft. We already know height = 21 so our equation looks like pi x 5^2 x 21

5^2 = 5 x 5= 25

so pi x 25 x 21 = 1649.34

sine

step-by-step explanation:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
