View related lesson
A
\(540cm^{2}\)
B
\(440cm^{2}\)
C
\(610cm^{2}\)
D
\(616cm^{2}\)
Ask EduPadi AI for a detailed answer
Correct Option: D
\[Surface\ area\ of\ a\ sphere = 4\pi r^{2}\]
\[diameter = 14cm\ \therefore radius = 7cm\ \]
\(Surface\ area\ of\ a\ sphere = 4 \times \frac{22}{7} \times \frac{7^{2}}{1} = 616cm^{2}\)
