Correct Answer

B. (6)

Step 1

Concept

In a sector, \(A=\frac{1}{2}rs\), and (A=3s) is given. Hence \(\frac{1}{2}r=3\), giving (r=6).

Step 2

Why this answer is correct

The correct answer is B. (6). In a sector, \(A=\frac{1}{2}rs\), and (A=3s) is given. Hence \(\frac{1}{2}r=3\), giving (r=6).

Step 3

Exam Tip

सेक्टर में \(A=\frac{1}{2}rs\) होता है और (A=3s) दिया है। इसलिए \(\frac{1}{2}r=3\) से (r=6) मिलेगा।
