Well perimeter is lengthx2 and widthx2 so 7x2=14
then 64-14=50
50÷2= 25
length=25
Compute the two volumes and subtract!
V Cylinder = pi * r^2*height
V1 = pi*8^2*15, V2 = pi*3^2*15,
V1-V2 = pi*15(8^2-3^2) = pi*15*55 = 2591.81393921157923
Answer = 2591.8 cm^3 (if rounded to tenths)
To solve, first add 25 to both sides to get
Then factor to get
There is only one solution, x = 5.
