Q1. Case study Based – 1
In festive season, Deepali bought Cylindrical jars and cubical boxes to fill her home-made cakes and chocolates. Each jar is 14 cm high and has a diameter of 11 cm.
(i) The volume of Cake that can be kept in each jar is​

Answer 1

Step-by-step explanation:

volume of a cylinder =πr²h

diameter=11 so radius = 11/2=5.5.

so a/c,

volume of the cake =22/7×55/10×55/10×14cm³

=22/7× 30.25×14cm³

=22/7×423.5cm³

=1331cm³

so

so the volume of the cake =1331cm³

Answer 2

Given:

In festive season, Deepali bought Cylindrical jars and cubical boxes to fill her home-made cakes and chocolates. Each jar is 14 cm high and has a diameter of 11 cm.

To Find:

The volume of cake that can be kept in each jar.

Solution:

We know that,

volume of a cylinder =πr²h

diameter = 11

So, Radius = 11/2 = 5.5 cm

According to the question,

volume of the cake = 22/7 × 55/10 × 55/10 × 14 cm³ = 22/7 × 30.25 × 14 cm³

                                 = 22/7 × 423.5 cm³ = 1331 cm³

Hence, the volume of cake that can be kept in each jar is 1331 cm³
