Question

the curved surface area of cone is 4070 centimetre square and its diameter is 70 cm what is its slant height ​

Answer 1

Step-by-step explanation:

Given that CSA of cone is 4070cm²

Diameter of cone = 70cm

Radius of cone = d/2=70/2=35cm

CSA of cone = πrl

πrl = 4070

22/7*35*l = 4070

22*5 l = 4070

110 l = 4070

l = 4070/110

l = 37 cm

Answer 2

Answer:

Step-by-step explanation:

Given that CSA of cone is 4070cm²

Diameter of cone = 70cm

Radius of cone = d/2=70/2=35cm

CSA of cone = πrl

πrl = 4070

22/7*35*l = 4070

22*5 l = 4070

110 l = 4070

l = 4070/110

l = 37 cm
