Step-by-step explanation:
Hopefully you can see what I did there.
The sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
<h3>Area of a sector</h3>The coloured portion of the circle is known as a sector. The formula for calculating the area of a sector is given as:
Area of a sector = θ/360 * πr²
where
θ is the central angle
πr² represents the area of a circle.
Therefore the best statement that explains the formula is expressed as the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
