Question

The radius of the base and the height of the right circular cone are 7cm and 24cm
respectively.Find the volume and total surface area of the cone.

Answer 1

Answer:

r = 7cm

h = 24cm ________

therefore, l = √(24) ²+(7) ²

________

= √ 576 + 49

___

=√625

= 25

Now,

Volume of cone = 1/3 πr²h

= 1/3 x 22/7 x 7 x 7 x 24

= 1232 cm³

Again,

TSA of cone = πr(l+r)

= 22/7 x 7 (7 + 25)

= 22 x 32

= 704 cm²
