Formula of Circle Area
A = π r2
Information
A = Area
r = Jari-jari
Formula of circumference Circle
C = 2πr
Information:
C = Circumference Circle
r = radius
Length of Circular Arc Formula
Arc length = a / 360 10 two phi r
Information:
a = large corner of the middle of the circle
r = radius
Formula of juring Area Circle
Juring Area = a/360 10 πr2
Information:
a = Large corner of middle of circle
r = radius
Formula of Circumference Juring Circle
Circumference Juring = length of arc + 2r
Information:
r = Radius
