Question

What is the surface area of the right cylinder with a height of 20 and a radius of 5

Answer 1

For this case we have by definition, that the surface area of a cylinder is given by:

$SA = 2 \pi * r * h + 2 \pi * r ^ 2$

Where:

A: It's the radio

h: It's the height

According to the given data we have:

$SA = 2 \pi * (5) * 20 + 2 \pi * (5) ^ 2\\SA = 200 \pi + 50 \pi\\SA = 250 \pi\\SA = 785 \ units ^ 2$

ANswer:

$785 \ units ^ 2$

Answer 2

Answer: The answer is 785.4
