Question

2. The base of a circular cylinder has a diameter of 10 yards. The height is 11 yards. What is the surface area of the cylinder, rounded to the nearest tenth? (a) 961.3 yd2 (b) 1131.0 yd2 (c) 502.7 yd2 (d) 747.7 yd2

Answer 1

Explanation:

surface area=2πrh+2πr²=2πr(r+h)

=2π×5(5+11)

=160π

≈505.7 yd²
