How to accurately measure the Diameter of a Ball

If you’re looking for advice on how to accurately measure the diameter of a ball such as a basketball, a bowling ball or a tennis ball, simply continue to discover a fuss free, easy to understand guide on measuring the diameter of a ball, of any size. As a bonus, you’ll also discover how to work out the volume of a ball.

How to measure diameter of a ball:

In order to calculate the diameter of a ball use a tape measure to measure the circumference of your ball. To measure the circumference of your ball wrap your tape measure around your ball once.

Once you’ve written down the number of your ball’s circumference divide the number which you have by pi. If it’s been a few years since you’ve graduated from school, pi = 3.14. Once you’ve divided your circumference by 3.14, you’ll successfully have calculated the diameter of your ball.

As an example, if you measure a yoga ball and its circumference measures 67.71 inches, the diameter of the yoga ball which you’re measuring will be 21.65 inches.

How to measure the diameter of a circle:

If you’re not looking to measure the diameter of a three dimensional ball and are looking to calculate the diameter of a two dimensional circle, you’ll need to use an alternate formulaic equation to find the number that you’re looking for.

To accurately find out the diameter of a circle, first figure out the radius of your circle. The radius of a circle is the distance between the center point of your circle and the outside of your circle. Once you’ve found the radius of your circle, multiply the number which you have by 2 and then multiple the number which you get with pi which is 3.14.

If you’re curious as to why it’s a better idea to calculate the diameter of a circle by first finding the radius of your circle, instead of your circle’s circumference, the answer is that you should find it a lot easier to accurate measure your circle’s radius with a ruler than to try and measure the circumference of your circle.

The answer is that you should find it a lot easier to accurate measure your circle’s radius with a ruler than to try and measure the circumference of your circle. This method is used in making Pavers And Turf also

How to measure the volume of a sphere:

If you’re also interested in calculating the volume of a three dimensional sphere such as a ball, you can also use the following equation to figure out the volume of your ball. V = r. In this equation, V = volume and r = the radius of your ball or sphere.

Firstly you’ll need to find out the radius of your sphere. Next, cube your radius and multiply your cubed radius by 4/3. Now your equation should read V = . Lastly multiple your equation by pi which is 3.14 and you should get your answer and the volume of the sphere which you’re measuring.

So if you ever need to accurately measure the diameter of a sphere, such as a ball or a circle. Or you need to work out the volume of a sphere, it’s well worth using the simple equations listed above to find out the answers to your questions.
