Question

1. The radius and slant height of the cone are 5 cm and 10 cm respectively
Find the curved surface area.
(t = 3.14)​

Answer 1

curved surface area= πrl

3.14*5*10=157

Answer 2

Answer:

Step-by-step explanation:

Radius (r)=5 cm

Slant Height (l)=10 cm

Now,we know that curved surface area of cone=Area of the sector

                                                                                =пrl

                                                                                = 3.14×5×10

                                                                                =15.7×10

                                                                                 =157 cm²
