Answer:
V = πr³ + 2πr²
Step-by-step explanation:
Volume of a cylinder:
V = πr²h
with radius r and height h = 2 + r:
V = πr²(2 + r) = πr³ + 2πr²
Answer:x=2
Step-by-step explanation:
change () to x
x + -8= -6
-6+8=2
x=2
I know for a fact B is wrong, so you can mark that off. I got C.
Step-by-step explanation:

Distribute into 5x² into (3x +2).

The simplified expression is <em>15x³ + 10x²</em>
So, this would be a common circle question.
First, 20 degrees from a circle's curcumference would be 20/360, which is 1/18.
This means that the length of the arc of AB should be 1/18 of the circumference.
The formula for the circumference it 2pi*r
2*pi*27=54pi
54pi* 1/18= 6 pi
