The radius of a hemisphere having total surface area of 1848 sq. cm is 7 cm.

Question

Options:

A . True

B . False

Answer: Option B
:
B
Total surface area

= 3 π r^{2}

\Rightarrow 3 \times \frac{22}{7} \times r^{2} = 1848

\Rightarrow r^{2} = \frac{1848 \times 7}{3 \times 22}

\Rightarrow r^{2} = 196

\Rightarrow r = 14

cm
Thus, above statement is false.
