Calculate the area of the ball with a diameter of 12 metres
The diameter was 26 cm.
cubic metres
Surface area of the ball = 4*pi*342 = 4624*pi square mm
8.86683 square inches. (Area=4 X pi X radius squared) diameter of ball = 1.68 inches.
the more surface area, the more friction, the more the drag
First, you have to calculate the ball's volume. Just divide the mass by the specific gravity. Then use the formula for the volume of a sphere. Solve for r (radius). The diameter is twice the radius.
The average diameter of a ping pong ball is 40mm. I used this to calculate the area of the ball. V=(1/6)(pie)d^3 =(1/6)(3.14)(40x10^-3)^3 =0.00003349m^3 =33.493333cm^3 1cm^3=1ml as a reference
The width of a ball is its diameter, so the diameter of a ball that is 24 cm wide is 24 cm.
Ball area formula : 4*Pi*r2 For Example : r = 2 mm Calculation = 4*3.14*(2)2 = 3.14*16 So the area of the ball = 50.26 mm2
22179.7 when the diameter of a ping pong ball is 40 mm I found the area of a ping pong ball and divided 300 sq ft by the area of one ping pong ball.
The diameter of a standard tennis ball is approximately 6.7 cm.
=4 * Pi * R * R When R= Radius of the ball Pi= 22/7
