Answer:
640.5 cm^2
Step-by-step explanation:
So the formula for trapezoid is height times the average of the bases. So 25+36=61, and then we divide that by 2 to get 30.5 as our average. Then, we take 30.5 and multiply it by 21 and we get 640.5.
Answer:
Step-by-step explanation
Volume of tank = l* b*h
= 18*16*13
=3744 cubic cm
Volume of cylinder = volume of tank
πr²h = 3744
3.14* (17/2)² * h = 3744
h= 3744 *2 *2/*17*17*3.14
h=16.5 cm
