Surface area=4pie radius^2
Radius=10.5 cm
Surface area=4 multiple 22/7 multiple 10.5 /10 multiple 10.5/10
=88 multiple 15.75
=1386 cm Answer

Given:-

  • Radius = 10.5 cm

To find:-

  • The surface area

Answer & Explanation:-

R = 10.5 cm

SA = 4\pi r^2

\implies\displaystyle{4\times \frac{22}{7}\times \frac{10.5}{10}\times \frac{10.5}{10}}

\implies\displaystyle{\frac{88\times 15\times 105}{100}}

Therefore, the surface area of sphere = 1386 cm².
