Webb10 aug. 2012 · formula for circumference is 2 (pi) (radius) therefore: 10=2 (pi) (radius) solving: radius = 10 / (2 pi) radius = 1.59 How do you find a circumference of a circle if … WebbThe volume of a sphere is just 2/3 the volume of a cylinder. Remember, the formula for the volume of a cylinder is π r 2 h. π is pi, which we can approximate to 3.14. 'r' is the radius, and 'h' is the height of the cylinder. V stands for volume and the red V is the volume of the sphere. But 'h' is the height of the cylinder, and we need ...
