Answer: 376.8m^2
Step-by-step explanation:
The surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, given as 3.14; h is the height, given as 7m and r is radius, given as 5m.
Therefore, rh = 5 x 7= 35m while r^2 =5×5 = 25m.
Slot the values into the formula:
V= 2 x3.14 (35) + 2 x 3.14 (25)
V = (6.28 × 35) + (6.28 x 25)
V = 219.8 + 157
V= 376.8m
