Answer:
<h2>A) 3 cm</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:

r - radius
H - height
We have r = 1cm and H = 21cm. Substitute:

The formula of a cone:

r - radius
H - height
We have V = 21π cm³ and H = 7cm. Substitute:
<em>divide both sides by π</em>
<em>divide both sides by 7</em>
<em>multiply both sides by 3</em>

Answer: 8.5%
7/82=0.0853
Multiply by 100 to get percentage
0.0853 x 100 = 8.53
I think the answer would be x= 4/7 y = +-16/7
Yes I got an A in college algebra...
