Find SA & Volume

Dimensions: Diameter=5in

Radius=2.5

R of core=1.625

D of core=3.25

Thought Process:

We found the surface area of the roll and then subtracted the area of the 2 inner circles. Then we found the surface area of the core, subtracted the two circles and added the two surface areas together to find the surface area of the figure. For volume we found the volume of the roll and then the volume of the core and subtracted the role from the core to get the overall volume

Surface Area~267.723

Volume~189.52
