Question

the ratio of the radius of the base of a cylinder to its height is 7:6 if the volume of the cylinder of the cylinder is 294 pie cm cube, then its base is                                 friends i post many question and get my answers pls. provide me the answer of ths question also

Answer 1

volume of cylinder=294 pie cm3
from relation:-
pie r2 ×h=294 pie
r×r×h=294
r×r×6r/7=294(since6r=7h so h=6r/7)
6r cube(or cm3)=294×7
r=7cm
base(if perimeter)=2×pie×r
=2×22/7×7
=44cm
base(if area)=pie r2
22/7×7×7
=154cm2
