area = πr² = 154 r² = 154/π = 49 r = 7 cm
Area of circle = pie * r^2 154 = 22/7 * r^2 r^2 = (154*7)/22 r^2 = 7 * 7 r = 7
Radius of circle is 7 cm
Construct a circle of radius 1. From a point on the circle, construct another circle of radius 1. Inscribe a square where the two circles overlap. What is the area of the square?
A circle has a radius of 12 units and its center is at one vertex of a square. The square has a side of 12 units. Find the area of the shaded region?
A circle contains two tangent semicircles whose diameters are parallel chords. If the circle has an area equal to 1, what is the combined area of the two semicircles?
The blue figure is made of five quarter-circle arcs (each with integer radius) and a segment of length 4, which is the base of a square grid.
What is the area of the blue figure?
