We know that,


➡️ Surface area of sphere = 4 pie r^2

================================

Diameter of sphere = 14 cm

Radius of sphere = 14 / 2 = 7cm

Surface area of sphere $\4 \pie {r} ^{2}$

= 4 × 22/7 × 7 × 7 =
➡️ 516 cm

===============================

Diameter of sphere = 21 cm

Radius of sphere = 21/2 = 10.5 cm
