a shorter radius would mean a shorter track distance. The smaller the radius - the smaller the circumference.
Outer radius minus inner radius Subtract the inside diameter from the outside diameter, then divide the difference by 2.
You must use the relationship between the inner radius and the outer radius. The relationship could very well be different every time you run into a problem like this, and I can't answer the question this time because you haven't described any relationship between them.
The inner radius is 6 cm, and the outer radius is 9 cm. The circumference of a circle is given by the formula C = 2πr. Therefore, the inner circumference is 2π(6) = 12π cm, and the outer circumference is 2π(9) = 18π cm. The difference between the outer and inner circumferences is 18π - 12π = 6π cm.
Inner? Do you mean medial? It is ulna.

The inner and longer bones of the human forearms are called the ulna and the radius.
Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]
There is a rather large asteroid belt between Mars (the last inner planet) and Jupiter (the closest outer planet.) Mostly, however, the terminology refers to the vast difference in orbit radius between the inner and outer planets.
The thickness of the inner core is 1,200 km. 1,200 km being the radius of the sphere known as the inner core.
The inner radius of the stratosphere is about 10 kilometers, while the outer radius extends up to 50 kilometers. The volume of the stratosphere can be estimated by using the formula for the volume of a cylinder, since the stratosphere can be approximated as a cylindrical shape.
x^2+y^2=36
The inner circle is x2 + y2 = 4. The radius of the inner circle is the square root of 4, which is 2. To find the radius of the outer circle, multiply 2 times 4. The radius of the outer circle is 8. Square 8 (82 or 8 x 8) to find the number to put into the equation of the outer circle. This is 64. The equation for the outer circle is x2 + y2 = 64.
