Question

a storage drum in the shape of a cylinder is 3 feet tall and has a diameter of 4 feet. what is the total surface area of the storage drum? use 3.14 for pi and round the answer to the nearest tenth

Answer 1

Answer:

$SA=62.8\ ft^2$

Step-by-step explanation:

we know that

The surface area of a cylinder is equal to

$SA=2\pi r^{2}+2\pi rh$

we have

$h=3\ ft$

$r=4/2=2\ ft$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$SA=2(3.14)(2)^{2}+2(3.14)(2)(3)$

$SA=62.8\ ft^2$

Answer 2
