The radius of a sphere is 14 cm. What is the surface area of this sphere? [Use $$\pi=\frac{22}{7}$$]
The radius of a sphere is 14 cm.
Surface area of this sphere =Â $$4\times\ \pi\ \times\ \left(radius\right)^2$$
= $$4\times\ \frac{22}{7}\times\ \left(14\right)^2$$
= $$\frac{88}{7}\times\ 196$$
=Â $$88\times28$$
=Â 2464Â $$cm^{2}$$
