Base = 6 m

A. 150.72 + 56.52

B. 36 * 8

C. 150.72 + 226

D. 6 * 8 * 3.14

1 answer

The correct expression that would provide the approximate surface area of the cylinder is:

S.A. = 2*pi*r*h + 2*pi*r^2

Here, the given values are:

Height (h) = 8 m
Base (r) = 6 m

Let's calculate the surface area using the given formula:

S.A. = 2*pi*(6)*(8) + 2*pi*(6)^2

S.A. = 2*pi*48 + 2*pi*36

S.A. = 96*pi + 72*pi

S.A. = 168*pi

Since the surface area is given in square units, we can approximate pi as 3.14. Therefore,

S.A. ≈ 168 * 3.14
S.A. ≈ 528.72

Therefore, the correct option is A. 150.72 + 56.52
