Answer to Problem 18E
10 m
Explanation of Solution
Given information:
Radius( r ) of the cylindrical prism is 9 meters Height( h ) of the cylindrical prism is unknown Volume( V ) of the cylindrical prism is 254 m3
Formula used:
Volume( V ) of the cylindrical prism =
Calculation: substituting value of Radius ( r ) and Volume( V ) in the cylindrical prism volume formula to calculate height( h ) of the cylindrical prism,
Square of 9 is 81
And the value of pi upto 2 decimal points is 3.14
on multiplication gives answer as 25.12
On solving answer is,
h 10.11 m
Hence, height( h ) of the cylindrical prism is
h= 10 m
