Spherical Volume Formula – Having previously discussed the material regarding formula for the surface area of a balloonk then material basic math formula This time I will continue by showing a material that is still related to standing space. This post will provide clarification on how to calculate the formula for the volume of a sphere. not only that, as usual at the end of the discussion, some examples of questions and their discussion will be given so that you can understand how to use the formulas taught. Hopefully this discussion can help you understand how to find out the volume of a standing ball room and be able to work on school problems related to this material.
The formula for finding the volume of a sphere
Of course, you are already familiar with the ball because we often find objects that have the shape of a ball ranging from basketball to bekel balls and there is also a globe. then actually how to calculate the volume or content of a standing spherical space? this is his formula:
Volume of ball = 4/3 xr️
The volume formula if is very similar to the volume of a cone because the area of the cone is equal to half of the volume of a sphere.
Then how to use the formula to do the problem? see some pattern questions below:
Examples of Spherical Volume Formulas and Their Solutions
Example Question 1
If the radius of a basketball is 7 cm, if = 22/7 then what is the volume of the basketball?
V = 4/3 x r³
= 4/3 x 22/7 x 7³
= 4/3 x 22/7 x 343
= 1437.3 cm³.
So, the volume of the basketball is 1437.3 cm³.
Example Question 2
A rubber ball has a diameter of 24 cm. what is the volume of air in the ball?
Because what is known is the diameter, we first convert it to the radius. because the radius = 1/2 of the diameter then if the diameter is 24cm the radius is 12 cm.
we just plug it into the formula:
V = 4/3 x r³
V = 4/3 x 22/7 x 12³
V = 4/3 x 22/7 x 1728
V = 7234.56 cm³
Then the total volume of air in the rubber ball is 7234.56 cm³.
That’s the final material how to calculate the formula for the volume of a sphere complete with a pattern of questions and a discussion of how to answer the questions given. Hopefully now you can understand more about this formula for finding the volume of a sphere and how to use the formula in solving problems about the volume of a sphere. Thank you for listening to this material to the end, keep up the good work.
