Answer 2

We have given that ≈

• Circumference of circy=2πr=22cm
• Height =3m = 300cm

2πr=22

2×22/7×r=22

r= 22×7/22×2

r= 7/2

Curved surface area of cylinder ≈

• 2πrh where r is radius and h is height

2πrh=2×22/7×7/2×300

=6600 cm^2

Hence the curved surface area of cylinder =6600cm^2.✔️✔️✔️

________________________

another method CSA of cylinder = 2πrh

here, 2πr=22cm

h=300 cm

CSA=6600 cm^2
