7 non-overlapping unit circles are inscribed inside a large circle as shown below. Find the area of the shaded region?
1/9 the larger circle hence = pi sq units
Let the diameter of the 7 circles be "d" so the shaded area is:
((1.5d)^2 pi) - ((d/2)^2pi x 4) - (3 x (square root of 3)/2
Seven circles, each with radius 1, overlap to form the composite figure shown below. Find the area of shaded region?
In a circle of radius 1, an equilateral triangle is inscribed in the circle as shown. What is the area of the blue region?
In a unit square, two quarter circles are drawn, centered at two opposite vertices, What is the area of the oval-shaped region?
Three circles of unit radius and touching each other. What is max possible area of blue circle as shown in image? And what about red circles?
A rectangle has a side length equal to 10.
Two semicircles are constructed with their diameters equal to the length of 10 and along opposite sides of the rectangle, as shown.
A circle is inscribed between the intersection points of the semicircles and tangent to the two sides of 10 on the rectangle.
What is the area of the shaded region in which the two semicircles are overlapping?
