Question

the find the radius and total surface area of a cone whose curved surface area is 10010 CM square and slant height is 91 cm

Answer 1

CSA of cone= πrl
10010=22/7*r*91
r = 10010*7/91*22
r = 35
TSA of cone= πr[l+r]
               = 22/7[91+35]
               =22/7[126]
               =396 cm²
