Circle Calculators
Circle Area
-
Computes the area of a circle given the radius
(A = π r
2
)
.
Area of Circle Arc Segment f(r,θ)
-
Computes the area of an arc segment of a circle given the radius (
r
) and angle (
θ
)
Area of Circle Arc Segment Area f(r,h)
-
Computes the area of an arc segment of a circle given radius (
r
) and the depth (
h
)
into the circle.
Area of Circle Sector f(r,Θ)
-
Computes the area of a sector (pie slice) of a circle given the radius (
r
) and angle (
Θ
).
Angle of Circle Sector f(r,h)
-
Computes the angle in a circle from the radius and depth of the chord.
Area of Circle Annulus
-
Computes the area of an annulus (ring) given the inner radius (
r
) and outer radius (
R
).
Radius of Circle from Center and a Point
-
Computes the radius of a circle given the center point (
h,k
) and any other point (
x,y
) on the circle
.
Circumference of Circle
-
Computes the circumference of a circle given the radius (
C = 2 π r
).
Circle Arc Length
-
Computes the length of an arc length on a circle given the radius (r) and angle (
Θ
)
Circle within a Triangle
-
Computes the radius of a circle inscribed within a triangle
given the length of the three sides (
a,b,c
) of the triangle.
Circle around a Triangle
-
Computes the radius of a circle that circumscribes a triangle
given the length of the three sides (
a,b,c
) of the triangle.
Circle Radius from Circumference
