Surface Area of cylinder = 8195.4 inches^2

Step-by-step explanation:

we are given:

Diameter of cylinder = 30 inches

Height of cylinder = 72 inches

We need to find:

Surface area of cylinder = ?

The formula used is:

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

We know radius = diameter/2

so, radius = 30/2 = 15 inches

putting values:

$Surface\,\,Area=2\pi rh+2\pi r^2\\Surface\,\,Area=2*3.14*15*72+2*3.14*(15)^2\\Surface\,\,Area=6782.4+1413\\Surface\,\,Area=8195.4$

So, Surface Area of cylinder = 8195.4 inches^2
