Find the area of sector of the length an arc and radius of which are 2

1.	Find the area of sector of the length an arc and radius of which are 2.2cm and 3.5cm respectively
Answer» Given: Length of ARC = 2.2cm. radius = 3.5cm. To Find: Area of sector. Formula Used: $\star \: {\bf\green{Area \: of \: sector = \frac{length \: of \: arc \: \times \: radius}{2} }}$ Solution: We know that, $\star \: \boxed{\sf\red{Area \: of \: sector = \frac{length \: of \: arc \: \times \: radius}{2} }}$ Placing values, $:\implies\mathtt{ \frac{2.2 \times 3.5}{2} }$ $:\implies\mathtt{ \frac{7.7}{2} }$ $:\implies\mathtt{3.85}$ $\sf\star \: \underbrace\orange{Area \: of \: sector = 3.85cm^2} \: \star$ HENCE, Area of sector is 3.85cm². ExtraShots: Area of circle = πr². Circumference of circle = 2πr. Area of sector = l × r / 2. length of arc = θ / 360 × 2πr. Area of SEGMENT = r² (πθ / 360 - sin θ / 2)
