2 circles intersect at point T if the smallest circle has a radius are 4 and c is the centre of the larger circle then the diameter of the larger circle must be
4
8
12
16
The diameter of the larger circle must be 8.
This can be determined by drawing the two circles, one with a radius of 4 and the other with an unknown radius. The two circles intersect at a point T. The distance from the center of the smaller circle to T is 4 (the radius of the smaller circle). Therefore, the distance from C (the center of the larger circle) to T must also be 4 (since the two circles intersect at that point).
So, the diameter of the larger circle is twice the distance from C to T, which is 8.
