Question

The height of cone is 16cm and it's base radius is 12cm the curvedsurface area and the total surface area of the cone p=3.14

Answer 1

Step-by-step explanation:

OA=16cm,AB=l

l=162+122=256+144

l=20cm

curved surface Area,

C.S.A=πrl=3.14×12×20=753.6cm2

Total surface Area,

T.S.A=πr(r+l)=3.14×12[12+20]=1205.76cm

Answer 2

Step-by-step explanation:
