If the radius of a hemisphere is 13
If the radius of a hemisphere is 13 \(\surd3\) cm, find its curved surface area.
यदि अर्धगोले की त्रिज्या 13\(\surd3\) cm है, तो इसका वक्र पृष्ठीय क्षेत्रफल ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
\(1014\pi cm^2\)
CSA of hemisphere = $ 2 \pi r^2 $
r = $ 13 \sqrt{3} $ cm
CSA = $ 2 \pi (13 \sqrt{3})^2 $
$ = 2 \pi 169 \cdot 3 $
$ = 1014 \pi \text{ cm}^2 $
$ 1014 \pi \text{ cm}^2 $
