ANSWER

A bucket in the form of frustum of a cone can hold 14245 cm3 of water the radii of top and bottom are 14cm and 10.5 cm respectively. Find the height of bucket.

Posted by Naitik Garg 7 years, 2 months ago

CBSE > Class 11 > Mathematics

1 answers

Yogita Ingle 7 years, 2 months ago

R = 14 cm
r = 10.5 cm
Let height of frustum be h cm

∴ Volume held by bucket = 14245 cm³
Also,

Volume of frustum = π(R²+Rr+r²)h/3
⇒ 14245 = 22× (196+ 147+110.25 )× h/(3× 7)
⇒ 453.25 h = 14245*21/22
⇒ 453.25 h = 13597. 5
⇒ h = 13597.5/453.25 = 30cm
