Question

the radius of a cone is 7 cms and its slant is 10 cms find the CSa

Answer 1

CSA=πrl
=22×7×10/7
=22×10
=220cm^2

Answer 2

Method of Solution:


Given :

✏ Radius of Cone = 7 cm

✏ Slant Height = 10 cm


To Find : Curved Surface Area of Cone


Answer :


Formula of Curved Surface Area of Cone = πrl

Now,


Curved Surface Area of Cone = πrl

✏ 22/7 × 7 × 10

✏ 22×10

✏ 220 Cm²



Hence, Required Value of Curved Surface Area of Cone is 220 cm².
