Circumference And Area Of A Circle
Muhtasari
The circumference is the distance around a circle and the area is the surface it encloses, both governed by the constant \(\pi\). Extend these to a slice of the circle and you can find an arc length and the area of a sector.
In this lesson you will calculate the circumference and area of a circle, and the arc length and area of a sector, by treating a sector as a simple fraction of the whole circle.
Malengo
- Calculate the circumference and area of a circle, and the arc length and area of a sector.
