Answer:
Capacity of the bucket : 48510 cm3.
Given:
➛The radii of the circular ends of a conical bucket are 28cm and 7cm.
➛Height is 45cm .
To Find:
The capacity of the bucket .
Solution:
We are given,
➛The radii of the circular ends of a conical bucket are 28cm and 7cm.
➛Height is 45cm i.e. h=45 cm.
Let, r and R be the radii of top and bottom end respectively.
⛬ r = 28 cm. and R = 7 cm.
We know,
The volume/capacity of the conical bucket is:
Hence capacity of the bucket : 48510 cm³
