Answer to Problem 17E
8 in
Explanation of Solution
Given information:
Diameter of the cylindrical prism is unknown Height( h ) of the cylindrical prism is 6 in
Volume( V ) of the cylindrical prism is 301 in3
Formula used: Diameter of top or base of cylindrical prism which is looks like
d
Rearranging above formula
Volume( V ) of the cylindrical prism =
Calculation: substituting value of Radius ( r ), Height( h ) and Volume( V ) in the cylindrical prism volume formula,
On Rearranging,
the value of pi upto 2 decimal points is 3.14
on substituting value of pi
square root of 15.97 upto 2 dcimal point is 3.99 and square root of 4 is 2
3.99 is approximate to 4
Hence, approximate answer is
=8 in
