Question

What is the density of the football

Answer 1

Answer:

Mass of the ball is .42 kg. The density of air is 1.2 kg/m3. The coefficient of drag for the football is 0.05 to 0.14.

Explanation:

I carried out an experiment, to find the density of a football. I first measured the diameter of a the ball (using a 1 meter ruler) which is 22cm, then I halved it to get the radius 11cm. My next step was to work out the volume of the ball; because it's in a shape of sphere. I used the formula volume = (4/3) · π · r3. I found the volume of the ball to be 5575.279763cm3. Then I found the mass of a football approximately 420g, after I used the formula density=mass/volume, 420÷5575.279763= 0.08kg/m3 rounding up.

Answer 2

$\large{\underline{\boxed{\tt Answer}}}$

What is density?

Density is a measure of the amount of information on a storage medium.

$\large{\underline{\boxed{\tt Explanation}}}$

⇒Mass of the ball is = $42 kg$.

⇒The density of air is = $1.2 kg/m3$.

⇒The cofficient of drag for the football is = $0.05 to 0.14$.
