Question 1031082: Please help me, tutors :)

A cylindrical can of soup has a volume of 170 cubic inches. The radius of the soup is found using the formula r=√V/πh, where r is the radius, V is the volume of the can, and h is the height of the can.

a.) If the height of the can is 6 inches, find its radius to the nearest inch.

b.) If the radius of the can is 3 inches, find its height to the nearest inch.

Identical to #1031062.

(a) You have the formula so you just make the substitution and evaluate.

(b) The skill is, "Solve for any variable in a formula".


The basic formula is V=h%2Api%2Ar%5E2, from which you can solve for h or solve for r. You are given one of them, as r=sqrt%28V%2F%28pi%2Ah%29%29. Question #b asks for h when V and r are given. SOLVE THE FORMULA FOR h. You need Multiplicative Inverse Property and Multiplication Property of Equality.
