Question

Which equation can be used to find the surface area of the cylinder?
d= 6 cm
h = 14 cm
S = 27114)? +2 (14)(6)
S=2(3)+2(3)(14)
S = 276)2 + 2 546)(14)
S-2013)² + 2 013)(14)

Answer 1

Answer:

$Area=[2(3)(14)+2(3)^2]\pi$ .

Step-by-step explanation:

From the given figure it is clear that

Height of the cylinder: $h=14\text{ cm}$

Diameter of the cylinder: $d=6\text{ cm}$

Radius of the cylinder: $r=\frac{d}{2}=\frac{6}{2}=3\text{ cm}$

We know that,

$Area=2\pi rh+2\pi r^2$

Substitute r=3 and h=14 in the above formula.

$Area=2\pi (3)(14)+2\pi (3)^2$

$Area=[2(3)(14)+2(3)^2]\pi$

Therefore, the required equation is $Area=[2(3)(14)+2(3)^2]\pi$ .
