Question

A circle has a diameter of 26 units what is the area of the circle to the nearest hundredth of a square unit

Answer 1

The area of the circle is
`530.93\ units^(2)`

Explanation:

we know that

The area of a circle is equal to

`A=\pi r^(2)`

we have

`r=26/2=13\ units` ----> the radius is half the diameter

assume

`\pi=3.1416`

substitute

`A=(3.1416)(13)^(2)=530.93\ units^(2)`
