Question

If angle of sector is $x^o$, then formula used to calculate area is

• A. $\frac{x^o}{360}\times \pi r^2$
• B. $2\frac{x^o}{360}\times \pi r$
• C. $\frac{x^o}{180}\times \pi r^2$
• D. $2\frac{x^o}{360}\times r^2$

Answer 1

The correct option is A $\frac{x^o}{360}\times \pi r^2$

If angle of sector is $x^o$ then formula used to calculate is $\frac{x^o}{360}\times \pi r^2$.
