MCQ
Two circles intersect each other such that each circle passes through the centre of the other. If the distance between their centres is 12, what is the radius of each circle ?
- A6 cm
- ✓12 cm
- C24 cm
- Dcan’t say
✓
Answer
Correct option: B.
12 cm
Let $C_1$ and $C_2$ be the centres of the two circles.
Radius of circle with centre $C_1=$ Radius of circle with centre $C_2=$ Distance between their centres $=C_1 C_2=12 \mathrm{~cm}$
Thus, the radius of each circle is $12 \mathrm{~cm}$.
Hence, the correct answer is $12 \mathrm{~cm}$.
