Question

Work out the surface area of this cylinder.

Answer 1

Explanation:

Total surface = πr² + 2πrh

Surface area = 22/7 × 6 × 6 + 2 × 22/7 + 25

So 22/7 × 12 + 44/7 × 25

Therefore this will give us 37.71 + 157.14

Therefore the total surface area of the cylinder is 194.85 cm².

Hope this helps
