A machine part is diagrammed in the figure below with the dimensions given in inches. If the centers of the circles lie on the same line parallel to the bottom of the part, what is the distance, in inches, between the centers of the 2 holes in the machine part?

In the figure, A B is the diameter of the circle and C D is a chord parallel to it. If A B=20cm, C D=12 cm. What is the distance between CD and the center of the circle?

A sphere with a diameter of 2 inches is resting on a table. If the distance from the center of the sphere to the edge of the table is 10 inches, what is the distance, in inches, between the point where the sphere contacts the table and the table edge ?

In the figure given below, O is the center of the circle. Chord CD is parallel to the diameter AB. If angleABC = 35^(@) , calculate angleCED .

Three circles with radii 1,2 and 3 inches are externally tangent to one another , as shown in the figure above . The area , in square inches , of the sector of the circle of radius 1 that is cut off by the line segments joining the center of that circle to the centers of the other two circles (the shaded area ) is

A uniform circular disc of radius a is taken. A circular portion of radius b has been removed from it as shown in the figure. If the center of hole is at a distance c from the center of the disc, the distance x_(2) of the center of mass of the remaining part from the initial center of mass O is given by
