Y = -3(2) +22
Y = -6 +22
Y = 16
In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
The volume is 905.32 i believe
12(12)=144, 144(3.14)=452.16, 452.16(6)=2712.96, 2712.96/3=904.32
