Question

Find the surface area of a sphere with a radius of 1 cm to the nearest tenth. (Do NOTtypeinany units in your answer.)

Answer 1

The area of the sphere is 12.6

Here, we want to find the area of the sphere given the radius

Mathematically, we can calculate the area of the sphere using the formula below;

`\begin{gathered} A\text{ = 4}*\pi* r^2 \\ r\text{ = 1 cm} \\ \pi\text{ = 3.142} \\ \text{Area of sphere = 4}*3.142*1^2=12.6cm^2 \end{gathered}`
