Which of the following is the surface area of the right cylinder below

a. 240pi^
b. 540pi^
c. 225pi^
d. 252pi^

The answer is 252 pi units.

Explanation:

The surface area of a right cylinder is

So, given height is = 15 units

Given radius is = 6 units.

So, putting these values in the formula, we get:

=

= units

Hence, the answer is option D.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
