Answer 2

$\large\underline{\underline{\sf Given:}}$

• Radius of sphere (R)= 10.5cm

$\large\underline{\underline{\sf To\:Find:}}$

• Surface Area Of Sphere (A) = ?

$\large\underline{\underline{\sf Solution:}}$

We know that,

$\large{\boxed{\sf Surface\:Area\:of\:Sphere(A)=4πr^2}}$

$\large\implies{\sf A=4×\dfrac{22}{7}×(10.5)^2 }$

$\large\implies{\sf A=1384.74cm^2}$

$\Large\underline{\underline{\sf Answer:}}$

•°• Area of sphere is 1384.74cm²
