(Assume that the car's efficiency remains constant.).. 24) Given two concentric circles, the radius of the larger circle is 60 units. This process continues indefinitely,
2) Every student in Ms. Arcs MA, AN , NB and MB are all semicircles.. 11 Two circles, one of radius 3 and the other of radius 5, are externally tangent and are internally tangent to
The diagram shows a white semicircle of radius r , inside of which two grey semicircles of radius r/ 2 are inscribed, inside of which four white semi- circles of radius r/ 4
A smaller circle, with centre at the intersection of the diagonals of the square, is tangent to each of the four larger circles.. Find the radius of the
Prove that the reflection of BC in the line P Q is tangent to the circumcircle of triangle
At a typical stage in this process, we’ve selected a point P with maximum y -coordinate, so any points at distance less than √ 3 from P must lie inside the semicircular region of
(b) The shaded region lies inside the circle and outside the hexagon and thus its area is determined by subtracting the area of the hexagon from the area of the circle. First we
Since the smaller circle passes through the centre of the larger circle and just touches the outer circle, then by symmetry, its diameter must equal the radius of the larger circle.
