Calculating the Capacity of the Well

Oct 13, 2025 by magicalceylontours.com 120 views

Introduction

A well is a vertical open cylinder that can be used for various purposes, including storing water. In this problem, we are given a well with a radius of 1.2 m and a height of 5 m. The well contains water up to a height of 3 m. We need to calculate the capacity of the well, the volume of water it contains, and the area that needs to be painted if the well has to be painted.

Calculating the Capacity of the Well

The capacity of a cylinder is given by the formula:

Capacity = πr^2h

where r is the radius of the cylinder and h is its height. In this case, the radius of the well is 1.2 m and its height is 5 m.

import math

# Define the radius and height of the well
r = 1.2  # in meters
h = 5  # in meters

# Calculate the capacity of the well
capacity = math.pi * (r ** 2) * h

print("The capacity of the well is {:.2f} cubic meters.".format(capacity))

Calculating the Volume of Water in the Well

The volume of water in the well can be calculated by multiplying the capacity of the well by the fraction of its height that is occupied by water. In this case, the water occupies a height of 3 m out of a total height of 5 m.

# Calculate the fraction of the height occupied by water
fraction = 3 / 5

# Calculate the volume of water in the well
water_volume = capacity * fraction

print("The well contains {:.2f} cubic meters of water.".format(water_volume))

Converting the Volume of Water to Liters

To convert the volume of water from cubic meters to liters, we can use the conversion factor 1 cubic meter = 1000 liters.

# Convert the volume of water to liters
water_volume_liters = water_volume * 1000

print("The well contains {:.2f} liters of water.".format(water_volume_liters))

Calculating the Area to be Painted

To calculate the area to be painted, we need to calculate the lateral surface area of the well. The lateral surface area of a cylinder is given by the formula:

Lateral Surface Area = 2πrh

where r is the radius of the cylinder and h is its height.

# Calculate the lateral surface area of the well
lateral_surface_area = 2 * math.pi * r * h

print("The area to be painted is {:.2f} square meters.".format(lateral_surface_area))

Conclusion

In this problem, we calculated the capacity of a well, the volume of water it contains, and the area that needs to be painted if the well has to be painted. We used the formulas for the capacity and lateral surface area of a cylinder to perform these calculations.

Discussion

The capacity of a cylinder is given by the formula:

Capacity = πr^2h

where r is the radius of the cylinder and h is its height. This formula can be used to calculate the capacity of any cylinder, including a well.

The volume of water in a cylinder can be calculated by multiplying the capacity of the cylinder by the fraction of its height that is occupied by water. In this case, the water occupies a height of 3 m out of a total height of 5 m.

To convert the volume of water from cubic meters to liters, we can use the conversion factor 1 cubic meter = 1000 liters.

The lateral surface area of a cylinder is given by the formula:

Lateral Surface Area = 2πrh

where r is the radius of the cylinder and h is its height. This formula can be used to calculate the area that needs to be painted if a cylinder has to be painted.
