Question

Which equation can be used to find the surface area of the cylinder?

d = 6 cm

h = 14 cm

S= 2(14)2 + 25(14)(6)

S=2(3)2 + 2(3)(14)

S=28(6)2 + 25(6)(14)

S=2643)2 +27(3)(14)

Answer 1

S = π( 2(9) + 2(3)(14))

Explanation:

Here we are to select which of the options best describe the equation that could be used to find the surface area of the cylinder.

Mathematically,

the surface area of a cylinder can be calculated using the formula

S = 2 π r^2 + 2 π rh

from the question, we have r as d/2 = 6/2 = 3cm and h = 14cm

We plug these two values into the equation above

Thus, we have

S = 2 * π * 3^2 + 2 * π * 3 * 14

S = π( 2(9) + 2(3)(14))
