Answer: 376.8m
Step-by-step explanation:
Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14, h is the height= 7m and r is radius= 5m
rh = 5m x 7m = 35m while
r^2 = 5m x 5m = 25m
Slot the values into the formula:
V = 2 x 3.14 ( 35) + 2 x 3.14 (25)
V= (6.28 x 35) + (6.28 x 25)
= 219.8 + 157
V= 376.8m
I hope this helps.
The answer is 376.99. The area is a cylinder is 2πr ^2+ 2πr h
