Solution:

(b) (a) for Mahesh,
Height of cylinder = 30 cm
and radius of cylinder =

25/{2\π

cm
∴Volume = π

\r^2

h
= π

×25/{2\π}×25/{2\π}×30

= 1492.8

\cm^3

(b) For Tina,
Height of cylinder = 25 cm
and radius of cylinder =

30/{2\π}

cm
Volume = π

\r^2

h
= π

×30/{2\π}×30/{2\π}×25

= 1791.40

\cm^3

Clearly, B > A.
