1.	A shopkeeper has one laddoo of radius 5 cm. With the same material, how many laddoos of radius 2.5 cm can be made.
Answer» Volume of a sphere = (4/3)πr³ Given, shopkeeper has one laddoo of radius 5 cm Volume of the laddoo = (4/3) × (22/7) × 5³ Now, From this one laddoo, laddoos of radius 2.5 cm are to be made. Volume of laddoo of radius 2.5cm = (4/3) × (22/7) × 2.5³ ∴ No. of laddoos of radius 2.5 cm that can be made = =\(\frac{(\frac{4}{3}\times\frac{22}{7}\times5^3)}{\frac{4}{3}\times\frac{22}{7}\times2.5^3}\) = 8

A shopkeeper has one laddoo of radius 5 cm. With the same material, how many laddoos of radius 2.5 cm can be made.

Answer»

Volume of a sphere = (4/3)πr³

Given,

shopkeeper has one laddoo of radius 5 cm

Volume of the laddoo = (4/3) × (22/7) × 5³

Now,

From this one laddoo,

laddoos of radius 2.5 cm are to be made.

Volume of laddoo of radius 2.5cm = (4/3) × (22/7) × 2.5³

∴ No. of laddoos of radius 2.5 cm that can be made =

=\(\frac{(\frac{4}{3}\times\frac{22}{7}\times5^3)}{\frac{4}{3}\times\frac{22}{7}\times2.5^3}\) = 8
