The diameter of a table tennis ball is 40mm, so its radius would be 20mm and its volume would be 33.5mm³, while the diameter of a golf ball is 50mm, so its radius would be 25mm and its volume it would be 65.4mm³

How to calculate the radius of golf and table tennis balls?

To calculate the radius of golf and table tennis balls we must take into account the following information:

  • Table tennis ball diameter: 40mm = 4cm
  • Golf ball diameter: 50mm = 5cm

According to the information we must use the following formula to calculate the radius:

  • R = Diameter/2

So the radius of these spheres would be:

  • R table tennis ball = 4cm ÷ 2 = 2cm
  • R golf ball = 5cm ÷ 2 = 2.5cm

How to calculate the volume of the golf and table tennis ball?

To calculate the volume of table tennis and golf balls we must take into account the formula to carry out this procedure:

  • V = [tex]\frac{4}{3} \pi r[/tex]³

So, to find the value of the volume we must substitute the value of "r" which means radius as shown below:

V Table tennis ball = [tex]\frac{4}{3} \pi 2[/tex]³

  • V = [tex]\frac{4}{3}[/tex] × 3.1415 × 8
  • V = [tex]\frac{4}{3}[/tex] × 25.13
  • V = 33.5mm³

V golf ball = [tex]\frac{4}{3} \pi 25[/tex]³

  • V = [tex]\frac{4}{3}[/tex] × 3.1415 × 15.62
  • V = [tex]\frac{4}{3}[/tex] × 49.07
  • V = 65.4
