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
Pick the expression that would provide the approximate surface area in square units of the Cylinder below. S.A.= 2*pi*r*h + 2*pi * r ^ 2
