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.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
