2x+3y=9
X=(y+2)
2(y+2)+3y=9
2y+4+3y=9
-4 -4
2y+3y=5
5y=5
Y= 1
Answer: 6 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cone= (1/3) π radius² height
Replacing with the values given and solving for r:
36π = (1/3) π r² 12
36π/ [(1/3) π 12]= r²
9 = r²
√9 =r
3 ft = r
Since:
Diameter = 2 x radius
Substituting r=3
D = 2x 3
D = 6 feet
