Question 1/3 Hard Mathematics Trigonometric Functions Angles Class 11 Level 69

(1) रेडियन की सही ज्यामितीय व्याख्या कौन सी है?

Which is the correct geometrical interpretation of (1) radian?

Explanation opens after your attempt
Correct Answer

A. जब चाप लंबाई त्रिज्या के बराबर होWhen arc length equals radius

Step 1

Concept

(1) radian is formed when (s=r). For definition based questions remember \(s=r\theta\).

Step 2

Why this answer is correct

The correct answer is A. जब चाप लंबाई त्रिज्या के बराबर हो / When arc length equals radius. (1) radian is formed when (s=r). For definition based questions remember \(s=r\theta\).

Step 3

Exam Tip

(1) रेडियन तब बनता है जब (s=r) हो। परिभाषा आधारित प्रश्नों में \(s=r\theta\) को याद रखें.

Question 2/3 Hard Mathematics Trigonometric Functions Angles Class 11 Level 69

लगभग (1) रेडियन कितने डिग्री के बराबर होता है?

Approximately (1) radian is equal to how many degrees?

Explanation opens after your attempt
Correct Answer

C. \(57.3^\circ\)

Step 1

Concept

(1) radian \(=\frac{180^\circ}{\pi}\approx57.3^\circ\). In approximation questions use \(\pi\approx3.14\).

Step 2

Why this answer is correct

The correct answer is C. \(57.3^\circ\). (1) radian \(=\frac{180^\circ}{\pi}\approx57.3^\circ\). In approximation questions use \(\pi\approx3.14\).

Step 3

Exam Tip

(1) रेडियन \(=\frac{180^\circ}{\pi}\approx57.3^\circ\) होता है। अनुमान वाले प्रश्नों में \(\pi\approx3.14\) लें।
