In the diagram below, there are 4 squares and 3 areas are known. What is the radius of the circle?
A circle contains 4 identical squares, as shown below. If each square has a side length equal to 2, what is the radius of the circle?
As shown in the diagram below, circle D is internally tangent to circle A and externally tangent to circles B and C.
If circle B has a radius of 2 and C has a radius of 1, what is the radius of circle D?
If in each square, the blue and red areas are equal then find out the ratio of radius between big and small circle?
Three squares are constructed on the three sides of an equilateral triangle. Each square has a side length equal to 1. A circle circumscribes the squares, as shown. What is the radius of the circle?
There are 10 squares that are constructed as shown in the diagram. Find the difference between blue and red angle in degrees.
