Please help me with this problem.
Tpy6a [65]

Answer:

5.6 meters

Step-by-step explanation:

V = pi r^2 h

We want to solve for h

Divide each side by pi r^2

V/ pi r^2 = pi r^2 h/ pi r^2

V/ pi r^2 =h

We know v = 440   pi = 22/7 and r = 5

440 / ( 22/7 * 5^2) = h

440 / (22*25/7) = h

440*7/550 = h

5.6 = h
