Question

Find the surface area of a cylinder with a height of 7 m and a base radius of 5 m.

Use the value 3.14 for π, and do not do any rounding.

Answer 1

The answer is 376.99. The area is a cylinder is 2πr ^2+ 2πr h

Answer 2

Answer: 376.8m

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.
