Question

!Cone and it's property!

Find the curved surface area of a right circular cone whose slant height is 10 cm and Base is 7cm. ​

​

Answer 1

Given, radius of cone = 7 cm and slant height = 10 cm.

So, curved surface area of cone = πrl = π × 7 × 10

= 70π cm^2

Hope it helps

Answer 2

Answer:

220square cm

Step-by-step explanation:

CSA of the cone=πrl

where l=10cm. r=7

πrl=22/7×7×10

πrl=22/7×7×10 =22/7×70

πrl=22/7×7×10 =22/7×70 =22×10

πrl=22/7×7×10 =22/7×70 =22×10 =220 cm^2
