Question

5. Assuming the average distance of the earth from the sun to be 149700000 km
and the angle subtended by the sun at the eye of a person on the earth to be
32', find the sun's diameter.​

Answer 1

Answer:

1 degree = 60 minutes

1 minute = 1/60 degree

360 degree = 2 pi radian

1 degree = pi /180 radian

32' = 32 minute = 32/60 degree

32' = ( 32/60 )*( pi/180 ) radian.....

Your answer is given by parallax method.........

R*( angle subtended at earth) = diameter of sun......

149700000000 m * 32' = calculate yourself by calculator by putting 32' in radians...... There is one more method of calculus in mathematics to solve this..... If you need I can help you.....
