Question

35 cm and height 12 cm.
. Find the volume, curved surface area and the total surface area of a
cone whose height is 6 cm and slant height 10 cm. (Take a = 3.14.)​

Answer 1

Answer:

Answer

h=6 cm,l=10 cm,π=3.14

OB=

Curved surface area of the cone =πrl+πr

2

=πr(l+r)=3.14

T.S.A=452.16 cm
