Question 68
The radius of a sphere is 14 cm. What is the surface area of this sphere? [Use $$\pi=\frac{22}{7}$$]
Solution
The radius of a sphere is 14 cm.
Surface area of this sphere = $$4\times\ \pi\ \times\ \left(radius\right)^2$$
= $$4\times\ \frac{22}{7}\times\ \left(14\right)^2$$
= $$\frac{88}{7}\times\ 196$$
= $$88\times28$$
= 2464 $$cm^{2}$$
