Question

on his birthday in the month of January harish distributed soup he had it in a cylindrical bucket with base radius 21 cm and height 98 cm he distributed the soup in a hemispherical bowl of radius 7 cm to the poor people and also gave a blanket to them how many people were served the soup??

Answer 1

No of people served = volume of cylindrical cintainer / volume of hemispherical bowl = Π r^2 h / 2/3 * Π r^3 = 21 * 21 * 98 / 2/3 * 7 * 7 * 7 = 189 …189 PEOPLE WERE SERVED

Answer 2

Answer:

188

Step-by-step explanation:

Radius of cylinder = 21 cm

Height of cylinder = 98 cm

Volume of cylinder = $\pi r^2 h$

                               =$\frac{22}{7} \times 21^2 \times 98$

                               =$135828 cm^3$

Volume of hemisphere = $\frac{2}{3} \pi r^3$

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

                                    = $718.67 cm^3$

No. of people served = $\frac{\text{Volume of cylinder}}{\text{Volume of hemisphere}}$

                                   = $\frac{135828}{718.67}$

                                   = $188.99$

So, no. of people served is 188
