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.

Answer:
The ratio between them is approximately , therefore the correct answer is A.
Step-by-step explanation:
In order to calculate the ratio of the diameter of the Sun to the diameter of the Earth we will first represent the Earth's diameter as a scientific notation, to do this we will add one to the power of ten for every time the comma walks to the left until there's only one number to the left. This is done to make the division easier,
The ratio is given by the Sun's diameter divided by the Earth's, as shown below:
The ratio between them is approximately , therefore the correct answer is A.
