diameter of cylindrical bowl = 7cm
Radius of cylinder “r” = 3.5cm
Height upto which the soup is filled “h” = 4cm
No. of patients daily = 250
we take π =
TO FIND : quantity of soup to be prepared daily in the hospital to serve 250 patients = ?
PROCEDURE :
Volume of a cylindrical bowl “V” = π r2h
Putting the values in the above formula, we get
V = × (3.5)2 × 4
V = ×3.5× 3.5× 4
= ×3.5×4
= 22× 3.5× 2
= 154cm3
∴ volume of 1 bowl = 154cm3
⇒ volume of 250 bowls = 250 × 154cm3 = 38500cm3
Quantity of soup in the 250 bowls = 38500 × litres
{∵ 1litre = 1000cm3)
Quantity of soup in the 250 bowls = litres = 38.5 litres.
∴ Quantity of soup in the 250 bowls is 38.5 litres.
