Word Problem:

 

Sophia wants to make a small decorative sphere for her art project. She decides to use a small foam ball with a diameter of 4 centimeters. Sophia wants to know the volume of the foam ball to determine how much paint she will need. Can you help her?

 

Solution:

 

To find the volume of the sphere, we can use the formula:

 

Volume of a sphere = (4/3) * π * radius³

 

Given that the diameter of the foam ball is 4 centimeters, we can find the radius by dividing the diameter by 2:

 

Radius = Diameter / 2 = 4 cm / 2 = 2 cm

 

Now, substituting the value of the radius into the formula, we have:

 

Volume of the sphere = (4/3) * π * (2 cm)³

 

Calculating the volume:

 

Volume of the sphere = (4/3) * 3.14 * 2³

                    = (4/3) * 3.14 * 8

                    = 33.49 cm³ (rounded to two decimal places)

 

Answer: The volume of the foam ball is approximately 33.49 cm³.

38-39

Word Problem:

 

Alex's family wants to keep track of their water consumption for the month. At the beginning of the month, their water meter reading was 150 cubic meters. After a month, the reading increased to 180 cubic meters. Can you help Alex determine how much water their family consumed during the month?

 

Solution:

 

To find the water consumption, we need to calculate the difference between the initial and final meter readings.

 

Water consumption = Final meter reading - Initial meter reading

 

Given that the initial meter reading was 150 cubic meters and the final meter reading was 180 cubic meters, we can substitute these values into the equation:

 

Water consumption = 180 cubic meters - 150 cubic meters

                 = 30 cubic meters

 

Answer: Alex's family consumed 30 cubic meters of water during the month.

[Q4] Finding the Volume of a Cone

Image
Exploring the Volume of a Cone: A Fascinating Mathematical Journey By Pj Miana   Hello, young mathematicians! Today, we embark on an exciting adventure into the world of geometry to unravel the mysteries of the volume of a cone. Get ready to dive deep into this mathematical concept and discover the wonders it holds!   What is a Cone?   Before we delve into its volume, let's first understand what a cone is. A cone is a three-dimensional shape that has a circular base and a pointed top, called the apex. Imagine an ice cream cone or a party hat, and you'll have a perfect visual representation of this versatile shape.   Watch also this video in tagalog:  Understanding Volume   Volume is the amount of space occupied by a three-dimensional object. In simpler terms, it's how much "stuff" can fit inside the object. For example, when you fill a glass with water, you're measuring its volume—the amount of water it can hold.   Formula for Finding
