Question

The radius and slant height of Cone is 2 cm and 6cm respectively its curved surface

area is ……….........cm².

a) 12 π b) 4 π c) 8 π d) 6 π​

Answer 1

Answer :-

Option (A) 12π cm².

Explanation :-

Given :

• Radius of Cone = 2 cm.
• Slant Height of Cone = 6 cm.

To Find :

• Curved Surface Area of Cone.

Solution :

We know that,

CSA of Cone = πrl.

We will substitute these values and we will get our answer.

➞ CSA of Cone = πrl.

➞ CSA of Cone = π × 2 × 6.

➞ CSA of Cone = 12π cm²

Hence, CSA of Cone = 12π cm².

So, Answer = Option (A) 12π cm².
