If \(\theta=2\) radians and (s=16) cm then what is the radius (r)?
Explanation opens after your attempt
C. (8) सेमी(8) cm
Concept
\(r=\frac{s}{\theta}=\frac{16}{2}=8\) cm. Rearrange the formula according to the required quantity.
Why this answer is correct
The correct answer is C. (8) सेमी / (8) cm. \(r=\frac{s}{\theta}=\frac{16}{2}=8\) cm. Rearrange the formula according to the required quantity.
Exam Tip
\(r=\frac{s}{\theta}=\frac{16}{2}=8\) सेमी होता है। सूत्र को आवश्यक राशि के अनुसार बदलें।
