As with circles, the radius of a sphere is often an essential piece of starting information for calculating the shape's diameter, circumference, surface area, and/or volume. Basically, for any rotating object, the moment of inertia can be calculated by taking the distance of each particle from the axis of rotation (r in the equation), squaring that value (that's the r 2 term), and multiplying it times the mass of that particle. Given a circumference of 10 inches, the diameter of the circle is approximately 3. In math we typically measure the x-coordinate [left/right distance], the y-coordinate [front-back distance], and the z-coordinate [up/down distance]. Increase the turning angle to 45 degrees, and turn radius decreases to 565 inches or 47 feet. A particle moving with a constant acceleration has a velocity of 20,0 cm/s when its position is x = 10.
