Question

find the volume of a right circular cylinder if - circumference of its base = 1.32 m, height =25cm

Answer 1

circumference of base=2pie*r
132cm=2pie*r
66*7/22=r
3*7=r
r=21cm
volume of cylinder=pie*r^2h
=22/7*(21)^2*25
=22/7*441*25
22*63*25
=34650 cm

Answer 2

$hey \: mate \\ \\ here \: is \: your \: answer \\ \\ the \: circumference \: of \: a \: circle\: is \: \\ equal \: to \: 2\pi {r } \ \\ \\ base \: = 1.32m \: height = 25 \:\\132\:= \:2×22/7×r\\r=\frac{132×7}{44}//r=21 (given) \\ \: radius \: \\ = \frac{d}{2} = \frac{42}{2} = 21cm \\ (\pi = \frac{22}{7} ) \: given. \\ \\ the \: volume \: of \: cylinder \\ \\ \pi {r}^{2} h = \frac{22}{7} \times ( {21})^{2} \times 25 \\ \\ = 34650\\ hope \: its \: helpful \: for \: you$
