प्रश्न
The radii of the ends of a bucket of height 24 cm are 15 cm and 5 cm. Find its capacity. (Take π = 22/7)
उत्तर
Height of a bucket = 24 cm
R= 15cm
r = 5cm
Therefore,
Capacity of the bucket
`=(pih)/3[h^2 + Rr + r^2]`
`=22/7 xx 24 /3 xx [(15)^2 + 15 xx 5 + (5)^2]`
`=8171. 42 cm^3`

The radius of a metal sphere is 3 cm. The sphere is melted and made into a long wire of uniform circular cross-section, whose length is 36 cm. To calculate the radius of wire, complete the following activity.
Radius of the sphere = `square`
Length of the wire = `square`
Let the radius of the wire by r cm.
Now, Volume of the wire = Volume of the `square`
`square` = `square`
r2 × `square` = `square` × `square`
r2 × `square` = `square`
r = `square`
Hence, the radius of the wire is `square` cm.
