Question

GOD PLEASE HELP ME. i really do need help.

Answer 1

Answer:

step below

Step-by-step 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

Answer 2

Answer:

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)

Step-by-step 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

$V=\pi r^{2} (\frac{h}{3} )\\V=\pi 7^{2} (\frac{15}{3})\\V=49 (5)\pi \\V=245\pi$
