The Correct Option is B
Solution and Explanation
Step 1: In a circle, the lengths of the tangents drawn from an external point to the circle are equal.
\[
PA = PB
\]
Since \( PA = 6 \, \text{cm} \), we have \( PB = 6 \, \text{cm} \).
Thus, the correct answer is \( \boxed{6 \, \text{cm}} \).

The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\))
Activity :
r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.
A(P-AXB) = \(\frac{\theta}{360} \times \boxed{\phantom{\pi r^2}}\) = \(\frac{\boxed{\phantom{90}}}{360} \times 3.14 \times 10^2\) = \(\frac{1}{4} \times \boxed{\phantom{314}}\) <br>
A(P-AXB) = \(\boxed{\phantom{78.5}}\) sq. cm.
