Question

a right angled triangle the sides of which are 20cm 21 cm and 29cm is made to turn the longest side find the vol. of the cone thus formod

Answer 1

Height of cone formed = 21 cm

Radius of the cone = 20 cm

Volume = pi *r^2 h /3

= 22 * 20 *20 * 21 /7*3

= 22 * 400

= 8800 cm^2

Answer 2

Step-by-step explanation:

ANSWER

Height of core formed = 21cm

Radius of the core = 20cm

Volume = πr2h/3

=22∗20∗20∗21/7∗3

=22∗400

=8800cm2
