Question

Find the surface area of a cylinder with radius r = 6 and height h = 14.8 to the nearest tenth of a square cm. Use π = 3.14

Answer 1

About 783.7 square cm.

Explanation:

The formula for the surface area of a cylinder is (2 * pi *r^2) + (2 * pi * r * h).

(2 * 3.14 * 6^2) + (2 * 3.14 * 6 * 14.8) = (2 * 3.14 * 36) + (2 * 3.14 * 6 * 14.8) = 6.28 * 36 + 6.28 * 88.8 = 226.08 + 557.664 = 783.744.

So, the surface area of the cylinder is about 783.7 square centimetres.

Hope this helps!

Answer 2

783.7 square units

Explanation:

The formula for the surface area of a cylinder is ...

A = 2πr^2 + 2πrh = 2πr(r +h)

Using the given numbers, the area is ...

A = 2(3.14)(6)(6 +14.8) = 783.7 . . . square units
