Question

The radius of the circle is $7$ cm and m $\left(\text{arc}RYS\right)={60}^{\circ }$, with the help of the figure answer the given question.

Area (P-RXS) is $128.33c{m}^2$
If true then enter $1$ and if false then enter $0$.

Answer 1

Area
of the complete circle $\pi r^2=\frac{22}{7}\times 7^2=154{cm}^2$
Area of the sector A (P-RYS) $=\frac{60}{360}\times \frac{22}{7}\times 7\times 7=25.67{cm}^2$
Hence, the area of the sector A (P-RXS) = Area of the complete circle - Area of the sector A (P-RYS)

$=154-25.67$

$=128.33{cm}^2$
