such that CD and CE trisect C. If
then tan B can be written as where m and n are
BE 15
n
relatively prime positive integers, and p is a positive integer not divisible by the square of any prime. Find
m +n + p.

c. 4 1/4 pounds

2 is the final ! : )

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
