Answer 1

for A

the radius is 3 and the height is 9

the volume of a cylinder can be found using pi * r^2 * h

so volume = ?

Answer 2

254.34?

Answer 3

did it say if it wanted exact answers or decimals?

Answer 4

usually we would just leave it as

81 pi

Answer 5

just to calculate the volume? ill put both

Answer 6

sure

Answer 7

for part B, the volume of the cone is just 1/3 the volume of the cylinder

Answer 8

so it would be 27 pi, or 84.82

Answer 9

what the formula?

Answer 10

for Part C, we would subtract the volume of the cone from the volume of the cylinder

Answer 11

volume of cone = 1/3 * volume of cylinder

Answer 12

and part D just wants you to show the actual math for part C

Answer 13

so

volume of cylinder - volume of cone = 81pi - 27 pi = your answer

Answer 14

let me know when you're ready to move to the second problem

Answer 15

Okay im ready! @Vocaloid

Answer 16

for 5 a

the angle x is just half of the arc length (110)

Answer 17

so x = ?

Answer 18

huh...?

Answer 19

55?

Answer 20

what is half of 110?

Answer 21

good

Answer 22

for 5b, you add the two outer arcs and divide by 2 to get x

(88 + 88)/2 = ?

Answer 23

i got 88?

Answer 24

good

Answer 25

for 5c, instead of adding, you subtract the two arc lengths and divide by 2

Answer 26

(90-20)/2 = ?

Answer 27

35

Answer 28

good, that's it

Answer 29

Thank you!!
