Observe the measures of pots In the given figure. How many jugs of water can the cylindrical pot hold?

cylindrical water pot fig 7.9
conical water jug fig 7.8

Answer:-

The problem provides the following information:

The code calculates the number of conical water jugs that the cylindrical pot can hold. This is done using the formula:

n = Volume of cylindrical water pot / Volume of conical water jug

The volume of a cylinder is given by the formula: V = πr^2h, where r is the radius and h is the height. The volume of a cone is given by the formula: V = (1/3)πr^2h, where r is the radius and h is the height.

Substituting the given values, we get:

n = (πR^2H) / [(1/3)πr^2h]

Simplifying this equation, we get:

n = (3R^2H) / (r^2h)

Substituting the given values, we get:

n = (3 * 7^2 * 10) / (3.5^2 * 10)

Simplifying this equation, we get:

n = 12

Therefore, the cylindrical water pot can hold water of 12 conical water jugs.

Solution

The Radius of the conical water jug, r = 3.5 cm 

Height of conical water jug, h = 10 cm

the radius of a cylindrical pot, R = 7 cm

Height of cylindrical pot, H = 10 cm

Let n be the number of jugs of water that cylindrical pot can hold.

[therefore n = frac{text{ Volume of cylindrical water pot} }{text{ Volume of conical water jug} }]
[ Rightarrow n = frac{pi R^2 H}{frac{1}{3}pi r^2 h}]
[ Rightarrow n = frac{3 times left( 7 right)^2 times 10}{left( 3 . 5 right)^2 times 10} = 12]

Thus, the cylindrical water pot can hold water of 12 conical water jugs.
