Katiyln and lewis share sweets in the ratio 7:1 if katliyn geta 21 sweets how many does lewis get

Step-by-step explanation:

Given Katiyln and lewis share sweets in the ratio =7:1

katliyn gets= 21 sweets

share of katiyln sweet =7x

share of Lewis sweet =X

So 7x=21 given

X=21/7

X=3

So Lewis gets x =3 sweets.

The formula for cylinder of pi is v = π r ^ 2 h.

So you are going to do pi x 6^2 x 12 = 1357.168026350791 then divide 1357.168026350791 by pi and you get C. 432 pi in.^2
