For this cylinder the radius r = 6.8 inches and the height L = 14.2 inches. Which is the BEST estimate for the volume? (Use π = 3.14)
A)
1686 in3
B)
1962 in3
C)
2008 in3
D)
2154 in3
The volume of a prism is given by $\displaystyle \text{ Cross Sectional Area } \times \text{ Length}$
For a cylinder the cross section is equal to that of a circle, hence the volume is given by $\displaystyle V = \pi r^2 l$
I get an answer of 2061.75 which doesn't seem all that close
