Question

The radius of a circular baking tray is 6 cm. Find its area correct to 2 decimal places. Use the π button on your calculator for π in your calculations.

Answer 1

`A \approx 113.10cm^2`

Explanation:

The circle is a flat surface or area limited or closed by a circumference. It is a two-dimensional figure and is formed by making a curve where it will always have the same distance to the center. Its area can be calculated using the following formula:

`A=\pi r^2\\\\Where:\\\\r=radius`

Therefore the area of the circular baking tray is:

`A=\pi (6)^2=\pi*36=36 \pi=113.0973355\approx 113.10 cm^2`
