Question

A cylinder has a height of 7 m and radius of 9 m. What is the surface area of the cylinder? Use 3.14 for pi and provide your answer accurate to two decimal places

Answer 1

The surface area of cylinder is 904.32 square meter

Solution:

The surface area of cylinder is given as:

$S.A = 2 \pi r(h+r)$

Where,

h is the height

r is the radius

From given,

h = 7 m

r = 9 m

Substituting the values, we get,

$S.A = 2 \times 3.14 \times 9(7+9)\\\\S.A = 56.52 \times 16\\\\S.A = 904.32$

Thus surface area of cylinder is 904.32 square meter
