Answer 2

Given-

Dimensions of rectangle= 22 cm× 6 cm

height of cylinder formed = 6 cm

To find-

Volume

Solution -

Circumference of circle = length of rectangle

2πr= 22

2× 22/7× r = 22

r = 22× 7/22× 1/2

r= 7/2 cm

r= 3.5 cm

Volume = πr²h

= Area of base circle × height

= 22/7×7/2×7/2× 6

= 11× 7× 3

= 11 × 21

= 231 cm²

Option (a)
