Which explanation justifies how the area of a sector of a circle is derived?
a. the area of a sector can be found by using the formula for the area of circle multiplied by how many angles are in the circle.
b. to derive the area of a sector, make a right triangle with the right angle located at the center of the circle. the angle of the triangle divided by the angles in a circle is 90360 . multiply the fraction by the area of the circle and then subtract the radius squared.
c. to find the area of a sector, divide the angle by the total amount of degrees in a triangle then multiply it by the area of the circle.
d. the area of a sector is part of an area of the entire circle. determine the fraction of the circle that the sector represents and multiply it by the area of the circle.
