- \(140\ \text{cm}^2\)
- \(150\ \text{cm}^2\)
- \(125\ \text{cm}^2\)
- \(200\ \text{cm}^2\)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Total area \(=\pi r^{2}=\frac{22}{7}\cdot 7^{2}=154\ \text{cm}^2\).
Major area \(=154-14=140\ \text{cm}^2\).
Major area \(=154-14=140\ \text{cm}^2\).

In the following figure chord MN and chord RS intersect at point D. If RD = 15, DS = 4, MD = 8, find DN by completing the following activity:
Activity :
\(\therefore\) MD \(\times\) DN = \(\boxed{\phantom{SD}}\) \(\times\) DS \(\dots\) (Theorem of internal division of chords)
\(\therefore\) \(\boxed{\phantom{8}}\) \(\times\) DN = 15 \(\times\) 4
\(\therefore\) DN = \(\frac{\boxed{\phantom{60}}}{8}\)
\(\therefore\) DN = \(\boxed{\phantom{7.5}}\)In the following figure, circle with centre D touches the sides of \(\angle\)ACB at A and B. If \(\angle\)ACB = 52\(^\circ\), find measure of \(\angle\)ADB.
