Question

When figuring out the arc length its:

(angle)/ 360 • pi • r²
and for sector its:
(angle)/360 • pi • 2r
or what-​

Answer 1

The arc length of a circle is given by the formula (angle/360) * 2π * r. For a sector of a circle, the formula is (angle/360) * π * r^2.

The arc length of a circle is given by the formula:

arc length = (angle/360) * 2π * r

Here, 'angle' refers to the measure of the central angle of the sector in degrees, 'r' is the radius of the circle, and π is a constant approximately equal to 3.14159.

For a sector of a circle, the formula is:

sector area = (angle/360) * π * r^2

This formula calculates the area of the sector, where 'angle' is the measure of the central angle in degrees, 'r' is the radius of the circle, and π is a constant approximately equal to 3.14159.
