If the surface area of a sphere

Surface area of a sphere is given by

$ \text{Surface Area} = 4 \pi r^2 $

Given surface area = $5544 \text{ cm}^2$ and $ \pi = \frac{22}{7} $.

Step 1: Substitute the values

$ 4 \times \frac{22}{7} \times r^2 = 5544 $

Step 2: Simplify

$ \frac{88}{7} r^2 = 5544 $

$ r^2 = \frac{5544 \times 7}{88} $

$ r^2 = 441 $

$ r = 21 \text{ cm} $

Step 3: Find diameter

Diameter $= 2r = 2 \times 21 = 42 \text{ cm}$

✅ Answer: 42 cm
