Answer:
9 cm
Step-by-step explanation:
Use the cone volume formula, V = 
r²
Plug in the volume and radius, and solve for h, the height:
V = r²
27 = (3²)
27
= 9
3 =
9 = h
So, the height of the cone is 9 cm
x/6+4= 15
Subtract 4 from both sides; 4s cancel each other out
x/6+4-4= 15-4
x/6= 11
multiply both sides by 6 to eliminate fraction (multiply by reciprocal of 1/6)
(x/6)(6)= (11)(6)
x= 66
ANSWER: x= 66

Answer: y= 5/4 + 3/2
Step-by-step explanation: Your equation is y=mx +b. You have to subtract the second y from the first y, and the second x from the first x to find the slope. This equation would be 4-(-1) over 2-(-2). So your slope will be 5/4. Now to find the y-intercept you can choose either (x,y) point. For example if you are using (2,4) you would do b= 4-(5/4)(2). b=3/2.
V=3.14*4/3*r^3
r=4/2=2
v=3.14*4/3*2^3=33.4933333
B
