The circle at eh top of a cylinder has a radius of 3.3 inches. the cylinder is 21 inches long. what is the volume of the cylinder?

V =718.0866 in^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h

The radius is 3.3 and the height is 21

V = pi (3.3)^2 * 21

V = pi (10.89) (21)

V =pi 228.69

We can approximate pi by 3.14

V = 3.14(228.69)

V =718.0866 in^3

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

c is the answer
