Math Formula For Volume Of A Sphere
Since you know the length of the diameter and that the radius is equal to half of the diameter you can conclude that the radius of the soccer ball equals 11cm because 22 2 11.
Math formula for volume of a sphere. Or if we just divide the sphere volume formula by 2 we can obtain a more general formula for hemisphere volume. And you also know that the ball has a diameter of 22cm. To calculate the volume of a sphere the following formula is used where v volume and r radius. Since you are concerned with filling the amount of space inside of the soccer ball you know that this problem can be solved using the volume of a sphere formula.
