Answer:
B and C. if you got them wrong let me know :3
We are given:

There seems to be nothing I can do to simplify this equation. However, I can factor out an
since they both have at least an
. Here is what we get:

This is in the simplest form I can get into. I cannot do anything more to simplify this expression. This is your final answer.
Answer is c as the equation for the volume of a cylinder is pi x r^2 x h which equated to pi x 25 x 11 which equals 275 and your units have to be cubed as it is volume.
1. D bc switch the 1/3 into 3/1, then 4 time 3/1 = 12. Basically 4 times 3 =12
2. D
