formula for circumference of circle, area of circle, minor arc, major arc, minor sector and major sector....with individual figure for every formula....
Answers
Step-by-step explanation:
Area of Sector = θ × π 360 × r2 (when θ is in degrees)
Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)
L = θ × π180 × r (when θ is in degrees)
A major arc is an arc larger than a semicircle. A central angle which is subtended by a major arc has a measure larger than 180°. The arc length formula is used to find the length of an arc of a circle; ℓ=rθ ℓ = r θ , where θ is in radian. Sector area is found A=12θr2 A = 1 2 θ r 2 , where θ is in radian.Sector Area = r² * α / 2
The area of a circle is calculated as A = πr² . This is a great starting point. The full angle is 2π in radians, or 360° in degrees, the latter of which is the more common angle unit.formula for circumference of circle, area of circle, minor arc, major arc, minor sector and major sector....with individual figure for every formula....
