There are four semicircle of a circle.
A semi-circle is bounded by the diameter and the part of the circumference is cut off by it.
So, a diameter always divided circle into two semicircle.
Hence, given statement is false.
In Fig. there are three semicircles, A, B and C having diameter 3 cm each, and another semicircle E having a circle D with diameter 4.5 cm are shown. Calculate the cost of painting the shaded region at the rate of ₹25 per cm2.
There are 3 semi circles which are arranged in such a manner that it forms a triangle, as shown in the figure below. If the radius of semicircle A is 4 cm and the radius of semicircle B is 7.5 cm, then find the radius of the semicircle C.
