Taking the sun’s distance as 1.4950 x 108 km and the angle subtended by the sun at a point on earth as half a degree. Approximately, the diameter of the sun is
1.304637 x 10 7 km
1.304637 x 10 6 km
1.403367 x 10 6 km
1.340637 x 10 6 km
The radian measure of 240o is
(4π) c
In a circle of diameter 40 cm, the length of a chord is 20 cm. The length of the minor arc of the chord is
20 1/21 cm
20 20/21 cm
20 3/5 cm
21 20/21 cm
If the arc of the same length in two circles subtend angles 75o and 120o at the centre, then the ratio of their radii is
5 : 8
4 : 5
8 : 5
3 : 5
The radian measure of 25o is
πc
