Answer:

Surface area I'm guessing.  1,130.4

Step-by-step explanation:

The formula for the surface area of a cylinder is: 2*pi*r^2 + 2*pi*r*h.

Plug in the values given.

2*pi*10^2 + 2*pi*10*8

628 + 502.4 = 1,130.4

(If you want the most precise value, use a calculator for pi instead of just 3.14.)

ANSWER

[tex]S A = 1130.4[/tex]

square units.

EXPLANATION

The given cylinder has a height of 8 and a radius of 10.

The formula for calculating the surface area of a cylinder is

[tex]S A = 2\pi \: r(r + h)[/tex]

We substitute r=8 and h=10 into the formula to get:

[tex]S A = 2\pi \: 10(10+ 8)[/tex]

[tex]S A = 360\pi [/tex]

Or using π=3.14

[tex]S A = 1130.4[/tex]

units square.
