How many radiuses does a cube have?
None. On;ly circles have radiuses.
What are tangent circles?
Tangent circles are circles that touch one another without crossing. The distance between the centres of the circles must be equal to the difference or the sum of their radii.
What is a minor arc in a circle?
It is the smaller of the 2 part divided between 2 radii
What is the Difference between the perimeteres of two concentric circles is 66 Find the difference between radius?
The formula for the circumference, (C) of a circle is C = 2πr.....where r is the radius. Let R be the radius of the larger circle and r the radius of the smaller circle. Then 66 = 2πR - 2πr = 2π(R - r) Then R - r = 66/2π = 33/π ≅ 10.504 The difference between the two radii is 10.504 (3dp)
