The mathematical equation for volume of a cylinder is pi times radius Squared Times height

The radius squared is 36

So 3.14 x 36 =113.04
Then you multiply 113.04 x 7 = 719.28.
Round that number and you get to 791.3.

So the answer is c

Find $y$ if the point $(-6,y)$ is on the line that passes through $(-1,7)$ and $(3,-2)$.

vichka [17]

Answer:

y = 18.25

Step-by-step explanation:

The 2-point form of the equation of a line can be used to write the equation of the line through the given points.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (-2 -7)/(3 -(-1))(x -(-1)) +7

y = -9/4(x +1) +7

For x = -6 this evaluates to ...

y = -9/4(-6 +1) +7 = (9/4)(5) +7 = 45/4 +7

y = 18 1/4
