Question

The radius of base of a conical capos 14 cm height 15 cm and slant height is 10 cm find it volume and total surface area

Answer 1

Answer:

The base radius of cone (r)=14cm.

Slant height (I) =50cm:.

Curved surface area of cone = πrl=

7

22

×14×50

=2200cm

2

And total surface area of cone =πr(1+r)

=

7

22

×14×(50+14)

=22×2×64

=2816cm

2

Hence, curved surface area 2200cm

2

and total surface area =2816cm
