   10 - (-2) ÷ [(20) + (-2)]   Simplify the double negative
    10 + 2 ÷ [(20) + (-2)]   Add 20 + (-2) = 20 - 2
           10 + 2 ÷ 18         Add 10 + 2
               12 ÷ 18          Divide 12 ÷ 18

Which of the following is the surface area of the right cylinder below?
Evgen [1.6K]
The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.


In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).


The formula is now 2π4h + 2π4^2.


Next, plug in the height, 8 for h.



Now we have 2π4(8) + 2π4^2, which is approximately 301.59.


The surface area is 301.59. (Unit of measure was not specified)
