Formulas for the circumference of a circle
WebAs we know, for a complete circle, the angle made at the center is equal to 2 or $360^\circ$. If is measured in degrees, then “the area of a sector of a circle formula” is given by; Area of sector $= \frac{\theta}{360^\circ} \times \pi r^2$ If is measured in radians, then “the area of a sector of a circle formula” is given by WebThe circumference of a circle is calculated using the formula: 2 x π x radius, where π is a mathematical constant, equal to about 3.14159.
