Find the area of sector of a circle with radius 6cm if angle of the sector is 70 degree

$\large\red{\underline{\underline{\bf{\blue{Solution}}}}}$

We know that,

$\implies \: Area \: of \: Sector \: = \frac{\pi \times {r}^{2} \times\theta}{360} \\ \\ \implies \: \frac{ \frac{22}{7} \times 6 \times 6 \times 70}{360} \\ \\ \implies \: \frac{ \frac{55440}{7} }{360} \\ \\ \implies \: \frac{7920}{360} \\ \\ \implies \: 22 {cm}^{2}$

Answer 2

Answer:

22cm²

Step-by-step explanation:

we know that area of sector is

area=θ/360 ×πr²

θ=70° , r=6cm

area=70°/360°×22/7×6×6

       =22cm²
