Question

If the radius of the base of a cylinder is 7 cm and the length is 10 cm, what is its curved surface area?
1️⃣ 70 cm
2️⃣ 440 sqcm
3️⃣ 440 cubic cm
4️⃣ 700 sqcm​

Answer 1

Step-by-step explanation:

Solution :

Radius of the base of cylinder r = 7 cm, height h = 10 cm

∴∴ Curved surface area of cylinder =2πrh=2πrh

=2×227×7×10=2×227×7×10

=440cm2=440cm2
