Question

Find the surface area of a cylinder with a base diameter of 6 yd and a height of 5 yd

Answer 1

To find the top and bottom circles you use:
2(pi x r^2)
- your r (radius) is half of the diameter so 3.

To find the part around it you use:
2 x pi x r x height

Circles: 2(pi x 3^2) = 56.5487
Rectangular around: 2 x pi x 3 x 5 = 94.2478

- then add them together
56.5487 + 94.2478 = 150.7965 yards^2
