Answer:

Explanation:

Lateral area is the sides so for this it's distance around x 3 . b/c the cylinder is 3 units tall... sooo

r= radius , d= diameter

circumference = distance around = 2
\pir or d
\pi = 16
\pi

Lateral area is 16
\pi*3 = 48
\pi

Surface area is the lateral area + the top and bottom

the area of a circle is
\pi
r^(2)

the area of this circle for the top is
\pi
8^(2)

64
\pi

times 2 b/c there is also a top and a bottom

128
\pi + 48
\pi = 176
\pi

surface area is 176
\pi
units^(2)

Volume of a cylinder is area of the circle base times the height.

the base is 64
\pi

time 3 = 192
\pi
units^(3)

Volume is 603.1857
units^(3)

note that two of the answer include pi, but you have that already put in for you in the answer so leave that part off.

Explanation:

The lateral area is formula for a cylinder is


2\pi * r * h

where r is radius and h is height.


2\pi * 8 * 3 = 48\pi

The surface area of cylinder is


2\pi * {r}^(2) + 2\pi * r * h


2\pi(64) + 2\pi(24)


128\pi + 48\pi


176\pi

Volume of cylinder is


\pi * {r}^(2) * h


\pi * 64 * 3


192\pi
