Correct Answer

A. \(\sqrt{9}\)

Step 1

Concept

The square of the new radius is (8+1=9), so the length is \(\sqrt{9}\). Remember that the length is written as \(\sqrt{9}\), not just (9).

Step 2

Why this answer is correct

The correct answer is A. \(\sqrt{9}\). The square of the new radius is (8+1=9), so the length is \(\sqrt{9}\). Remember that the length is written as \(\sqrt{9}\), not just (9).

Step 3

Exam Tip

नई त्रिज्या का वर्ग (8+1=9) होगा, इसलिए लंबाई \(\sqrt{9}\) है। ध्यान रखें कि लंबाई (9) नहीं बल्कि \(\sqrt{9}\) लिखी जाती है।
