Question

height of cone 10cm and radius 6.3cm find the curved surface area of cone​

Answer 1

Step-by-step explanation:

6.3x2=12.6 OK. it helped

Answer 2

Heigh of cone= 10cm

radius= 6.3cm

For CSA of cone we need L so we will take it out by L^2=H^2+R^2

L^2=10^2+6.3^2

L^2=100+39.69

=11.8190 cm

CSA of cone= πrl

= 22/7*6.3*11.819

=234.0162 cm^2

Therefore the Curved Surface Area of cone= 234.0162 cm^2
