Answer: See below

Step-by-step explanation:

The formula for volume is V= πr^2h

Plug in the values

5.5 ft / 2 = 2.75 ft

and h = height which is 8ft

So, V= (3.14)(2.75ft)^2(8ft) = answer!

Hope this helps! :)

Answer: $158cm^2$

Step-by-step explanation:

You can use the following formula to calculate the surface area of the right rectangular prism:

$SA = 2(wl +lh + hw)$

Where "w" is the width, "l" is the length, and "h" is the height.

Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.

Then, the surface of the right rectangular prism is:

$SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2$
