Answer:
FG = 18
Step-by-step explanation:
FG + GH = FH
FG + 31 = 49
Subtract 31 from each side
FG +31-31 = 49-31
FG = 18
First, lets just write down what we are given,
R of cone = R of cylinder / 2
H of cone = R of cylinder
Volume of a cone = pi*r^2*h/3
All we are asked is to show what the volume of the cone is with only the variable of r which is the radius of the cylinder( I'm guessing ). So,
pi*(r/2)^2*r/3
