Question

Find the area of sector whose radius is 7 with the given angle 120​

Answer 1

Answer:

51.33 cm²

Step-by-step explanation:

Radius=7 cm

Area of sector = Ф/360°Xπr²

Area = \frac{\theta}{360^{\circ}}\times\pi{r}^{2}

\implies\frac{120^{\circ}}{360^{\circ}}\times\frac{22}{7}\times{7}^{2}

\implies 51.33\:cm^{2}
