Jupiter is at a distance of 824.7 million km from the Earth. Its angular diameter is measured to be 35.72". Calculate the diameter of Jupiter.

Explanation

`theta = 35.72..`
l" = `4.85 xx 10^(-6)` radian `rArr 35.72.. = 35.72 xx 4.85 xx 10^(-6)` rad
`d = Dtheta = 824.7 xx 35.72 xx 4.85 xx 10^(-6) = 1.4287 xx 10^(5)` km
