Question

(E) None of these
13. If the height of a cylinder is 4 times its
circumference, the volume of the cylinder
in terms of its circumference c, is
(A) 41c
(B) 270
(C) 203
(D)
16
(E) None of these

Answer 1

let Circumference = c = 2πr

=> r = c/2π

h = 4c

=> volume of cylinder =

π r²h

= π × c²/4 π×π × 4 c

= c³/π

=> answer is e None of these
