Question

Calculate the total surface area of a solid sphere of radius $7\text{ cm}$ . [Take $\pi = \frac{22}{7}$ ]

Verified Answer

$616\text{ cm}^2$

Explanation & Step-by-Step Solving

Context: The surface area formula for a sphere is $A = 4\pi r^2$ : $A = 4 \times \frac{22}{7} \times 7^2 = 4 \times \frac{22}{7} \times 49 = 4 \times 22 \times 7 = 616\text{ cm}^2$
