Question

there are hundred student in a blind school Mr and Mrs Sohan wish to serve the milk they have to option for serving the milk option in a hemispherical bowl with the radius 10.5 CM made up of Eco Friendly material option B A cylindrical bowl with radius 7 cm and height is 30 cm made up of plastic how many litres of milk is required if option is taken find the total quantity of milk in litres if option B stick in which option is best for serving the milk and why​

Answer 1

Option A: 242550 cm³.

Option B: 462000 cm³.

Step-by-step explanation:

Option A:

The volume of milk is a hemispherical bowl with the radius 10.5 cm will be = $\frac{2}{3}\pi r^{3}$

= $\frac{2}{3}\times \frac{22}{7}\times (10.5)^{3}$

= 2425.5 cm³

So, for 100 students the volume of milk required is (2425.5 × 100) = 242550 cm³.

Option B:

The volume of a cylindrical bowl of milk with radius 7 cm and height 30 cm will be = $\pi r^{2}h$

= $\frac{22}{7}\times 7^{2}\times 30$

= 4620 cm³

Therefore, for 100 students the volume of milk required is (4620 × 100) = 462000 cm³.

Now, option A will be best for serving the milk as the volume of milk required in option A is less. (Answer)
