Question

Find the surface area of the cylinder to the nearest tenth of a square unit. Use Pi = 3.14.

Answer 1

508.3 m^2 to nearest tenth.

Explanation:

Radius of the circular top = 12.5 / 2 = 6.25 m.

Surface area = area of curved side + 2 * area of the circular ends.

= 2 * 3.14 * 6.25 * 6.7 + 2 * 3.14 * 6.25^2

= 262.975 + 245.3125

= 508.2875
