$40^{\circ} 20^{\prime}$ નું રેડિયન માપમાં રૂપાંતર કરો.
A
$\frac{121 \pi}{540}$
B
$\frac{121 \pi}{540}$
C
$\frac{121 \pi}{540}$
D
$\frac{121 \pi}{540}$
Solution
We know that $180^{\circ}=\pi$ radian.
Hence $\quad 40^{\circ} 20^{\prime}=40 \frac{1}{3}$ degree $=\frac{\pi}{180} \times \frac{121}{3}$ radian $=\frac{121 \pi}{540}$ radian.
Therefore $40^{\circ} 20^{\prime}=\frac{121 \pi}{540}$ radian.
