Question

the curved surface area of a come is 4070cm^2 and it's diameter is 70 cm . what is it's slant height.​

Answer 1

Answer:

37cm

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
