Tamil Nadu Board Solutions for Chapter: Measurements, Exercise 6: Exercise 2.1

For the sector with given measures, find the length of the arc, area and perimeter. $(\pi =3.14)$ central angle $120°, d=12.6 \mathrm{cm}$

From the measures given below, if the area of the sector is $k {\mathrm{m}}^2$, find the value of $k$.

If the central angle of the sector whose measures are given below is $k°$ then find the value of $k$.

Use $\left(\pi =\frac{22}{7}\right)$

If the central angle of the sector whose measures are given below is $\theta °$, then find the value of $\theta$. $\left(\pi =\frac{22}{7}\right)$

A circle of radius $120 \mathrm{m}$ is divided into $8$ equal sectors. If the length of the arc of each of the sectors is $k\mathrm{\pi } \mathrm{m}$, find the value of $k$.

A circle of radius $70 \mathrm{cm}$ is divided into $5$ equal sectors. Let the area of each of the sectors be $\mathrm{k\pi } {\mathrm{cm}}^2$. Find the value of $\mathrm{k}$.

Dhamu fixes a square tile of $30 \mathrm{cm}$ on the floor. The tile has a sector design on it as shown in the figure. If the area of the sector is $\mathrm{k} {\mathrm{cm}}^2$. Find the value of $\mathrm{k}$.

A circle is formed with $8$ equal granite stones each of radius $56 \mathrm{cm}$ and whose central angle is $45°$. If the area of each of the granite is $k {\mathrm{cm}}^2$, find the value of $k$. $\left(\pi =\frac{22}{7}\right)$
