Question

the volume and the radius of the base of right circular cone on 9240 cm and 21 cm​

Answer 1

Answer:

29 cm

Step-by-step explanation:

Volume of cone=1/3πr²h

9240 =1/3*22/7*21*21*h

=22*21

=462

h=9240/462

h=20 cm

slant height=L

L=√R²+H²

L=√441+400

=√841

L=29  

Slant height=29 cm
