Whoever answers first i will mark as brainiest

As shown in picture,

volume of cone V = base area x height x (1/3) = pi x (4/2)^2 x 6 x (1/3) = 8 x pi

volume of cup V = base area x height = pi x (3/2)^2 x 3 = 6.75 x pi

(all the volumes are in cubic inches)

A - Incorrect

24 pack of cups: V = 24 x 6.75 x pi = 162 x pi

21 pack of cones: V = 21 x 8 x pi = 168 x pi

162 x pi < 168 x pi

B - Correct

12 pack of cups: V = 12 x 6.75 x pi = 254.5 > 250

C - Correct

14 pack of cones: V = 14 x 8 x pi =351.9 > 350

D - Correct

Volume of cylinder 8 tall, 6 wide: V = pi x (6/2)^2 x 8 = 72 x pi

12 pack of cups: V = 12 x 6.75 x pi = 80.4 x pi > 72 x pi

Hope this helps!

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

there are infinitely many solutions.
