Question

The diameter of a circle is 5 meters. what is the area?Give the exact answer in simplest form.

Answer 1

The area of the circle is given by:

`A=(\pi\cdot d^2)/(4)`

Where d is the diameter, so:

`A=(\pi\cdot(5)^2)/(4)=(\pi\cdot25)/(4)=(25)/(4)\pi`

Answer:

`(25)/(4)\pi\text{ square meters}`
