Answer:13.5 inches
Step-by-step explanation:
Here, the volume of a right circular cone varies jointly as the altitude and the square of the radius of the base
So our equation for volume becomes
V = c*h*r^2
where 'h' is altitude and 'r' is radius of base and 'c' is constant
Putting the value of V,h,r,
we get,
154 = c*12*3.5*3.5
c = 22/21
Now we have volume = 77 cu and radius of the base =7/3, so putting the values we get,
77 = 22/21*h*7/3*7/3
or, h= 13.5
Hope it helps!!!
Answer:
scalene and obtuse. All sides are different lengths and it has an angle exceeding 90 degrees
Step-by-step explanation:
Answer:
First lets simplify the m's. So to simplify we can use this formula
x^n / x^b = x^(n-b)
So that means that 5--7 = 5+7 = 12. So we can cancel out the m at the bottom and get m^12. Seen as we have m^12 on only of one we can take advantage and answer that. But just to prove for the n's we can do same 4--2 = 4+2 = 6. So that also says n^6. So That proved that
