Question

If the surface area of a sphere is 616 cm square, find the diameter of the sphere

Answer 1

$the \: diameter \: of \: the \: sphere \: is \: 14 \: cm$

Answer 2

Answer:

→ Diameter = 14 cm

Step-by-step explanation:

→ Surface area = 4πr²

616 = 4πr²

4πr² = 616

2×2× 3.14 × r² = 616

${r}^{2} = \frac{616}{4 \times 3.14} \\ \\ {r}^{2} = 49 cm$

r = 7 cm

→ Diameter = 2 × r

→ Diameter = 2 × 7

→ Diameter = 14 cm
