2 pie r = 132
2* 22÷7 × r = 132
solve fo r
r = 21cm
vol = pie r square h
22÷7×21×21×22
22×21×3×22
2* 22÷7 × r = 132
solve fo r
r = 21cm
vol = pie r square h
22÷7×21×21×22
22×21×3×22

Circumfrence=2Лr
132=2(22/7)r
r=132(7/44)
r=21 cm
Volume of a cylinder=Лr²h
=22/7*(21)²*22
=22/7(441)(22)
=484*63
=30492 cm³
The volume of the cylinder is 30492 cm³
132=2(22/7)r
r=132(7/44)
r=21 cm
