Question

Recall the formula S A = 2 pi r squared + 2 pi r h.
216 pi inches squared
252 pi inches squared
630 pi inches squared
648 pi inches squared

Answer 1

Answer:

The surface area of a cylinder is $252\pi\ \text{inches}^2$.

Step-by-step explanation:

We have,

Radius of cylinder is 6 inch and its height is 15 inches.

The surface area of a cylinder is given in terms of the formula as :

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

Plugging all the values in above formula :

$A=2\times 3.14\times (6)^2 +2\times 3.14\times 6\times 15\\\\A=252\pi\ \text{inches}^2$

So, the surface area of a cylinder is $252\pi\ \text{inches}^2$.

Answer 2

Answer: The surface area for this cylinder is 252*pi square inches.

Step-by-step explanation:

The surface area of a cylinder can be calculated by using the following formula:

surface area = 2*pi*r² + 2*pi*r*h

Applying the data from the problem, we have:

surface area = 2*pi*(6)² + 2*pi*(6)*15

surface area = 2*pi*36 + 180*pi

surface area = 72*pi + 180*pi

surface area = 252*pi

The surface area for this cylinder is 252*pi square inches.
