Answer: r= 25/3
Step-by-step explanation:
r-4(r+6)=-49 distribute the 4
r-4r-24=-49 combine like terms
-3r-24=-49 add 24 to both sides
-3r=-25 divide by -3
r= 25/3 answer

Answer:
The volume of cylinder is:
49806.06 ft^3
Step-by-step explanation:
We are given a right circular cylinder with:
Height(h)=
and a diameter is 
times it's height.
i.e. 
times it height.
i.e. the diameter is given as:
We know that the radius of cylinder is half the diameter.
Hence, radius(r) of cylinder is:
The volume(V) of cylinder is given by:
Hence, the volume of cylinder is:
49806.06 ft^3
