सही विकल्प है : (B) 14 cm
Given :
Curved Surface area of hemisphere \(=1232 \mathrm{~cm}^2\)
Let the radius of hemisphere be r cm.
\(\therefore\) Curved Surface area of hemisphere \(=2 \pi r^2\)
1232 = \(=2 \times\frac{22}{7} \times r^2\)
\( r^2\) = \(\frac{1232 \times 7}{44}\)
\(\therefore r =\sqrt{196} \)
= 14 cm
Hence, the radius of the hemisphere will be 14 cm.
