If the diameter ( d) is equal to 10, you write this value as d = 10. The radius is half the diameter, so the radius is 5 feet, or r = 5. You can find the circumference by using the formula So, the circumference is about 31.5 feet around.

WebThe Area of a Sphere is equal to the Square of the Radius of the sphere multiplied by 12.566 ( 4 × π) or Pi times the Diameter squared ( π × D × D ). Area = 12.566 ⋅ R ⋅ R. Area = 4 ⋅ π ⋅ R 2. Area = π ⋅ D 2. This number …
WebThe radius, diameter, and circumference of a circle are all related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter. The value … Webwell, speed=abs (angular velocity)*r. and if you want to find the angular velocity. you would just divide the speed by the radius.the direction depends on the fact of being clockwise or not. if its clockwise, its negative and if its counter clockwise its positive.and the units are radians/sec.and its because that's how we derived the formula.
WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference.
