Question

GOD PLEASE HELP ME. i really do need help.

Answer 1

the first choice- volume of the cylinder is 735pi

and the 3rd choice the volume of the come is 1/3 pf 735pi (245 is 1/3 of 735)

Explanation:

Volume of the cylinder

`V=\pi r^(2) h\\V=\pi 7^(2) 15\\V=49(15)\pi \\V=735\pi`

Volume of the cone

`V=\pi r^(2) ((h)/(3) )\\V=\pi 7^(2) ((15)/(3))\\V=49 (5)\pi \\V=245\pi`

Answer 2

step below

Explanation:

volume of cylinder = Bh = πr²h = π*7²*15 = 735π

volume of cone =1/3 Bh =1/3 πr²h =1/3 π*7²*15 = 1/3 * 735π
