Given Question:-

The radius of a sphere is 1 cm what is its surface area? (π= 3.14)

Required Answer:-

Surface area of sphere is 12.56².

Explanation:-

Given:-

• Radius of the sphere is 1cm.
• Value of π(pi)= 3.14

To Find:-

• What is its surface area?

Syncing:-

Formula to be used:-

$\large{\boxed{\sf{\green{Surface \: area\:of\:sphere=4\pi r^{2} }}}}{\orange{\checkmark}}$

• So let us now enter all values and solve the equation.

$\implies\sf{4\pi r^{2} }$

$\implies\sf{4\times 3.14 \times 1^{2} }$

$\implies\sf 12.56cm^{2}$

So, the surface area of sphere is 12.56².
