Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
Correct Answer: Option C
Explanation:
Surface area of a sphere = \(4\pi r^2\)
= \(4 \times \frac{22}{7} \times 7 \times 7\)
= \(616 cm^2\)
Surface area of a sphere = \(4\pi r^2\)
= \(4 \times \frac{22}{7} \times 7 \times 7\)
= \(616 cm^2\)
