Answer:
210 ÷7 = 30
Step-by-step explanation:
We can round the numbers to numbers that make the math easier
I will round 208 to 210
We know 21 divide by 7 is 3
210 ÷7 = 30
This is very close to the actual answer.
208÷7 = 29.71428571........

Answer:
C. 8,624
Step-by-step explanation:
recall that the formula for circumference is
Circumference = 2πr  ( = given as 85 meters)
hence, 
85 = 2πr
r = 85/(2π)
given h = 15m
volume of cylinder 
= πr²h
= π (85/2π)² 15  (using calculator and assuming π = 3.14)
= 8628.58
Comparing with the choices, the closest choice (within rounding error) is C. 8,624
