PLEASE HELP I DONT UNDERSTAND ILL GIVE MORE IF ITS RIGHT

17ft

Step-by-step explanation:

What you're going to do is solve this backwards so to find volume the eqation is v=(pir^2)h, so what you're going to do is:

833pi=(pi7^2)h                 you cross out pi and square 7                           833=49*h                         then you divide 49 from both sides and get 17

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

a is the right answer
