Angular diameter of the Jupiter is $$36"$$. If the distance of the Jupiter form the Earth is $$825$$ million kilometer, find the diameter of Jupiter.


SOLUTION
Let the diameter of jupiter be $$d \; m$$.
Distance of jupiter from the earth $$\left( D \right) = 825 \times {10}^{6} \times  {10}^{3} m = 8.25 \times {10}^{11}$$
Angular diameter $$\left( \theta \right) = 36' = 36 \times 4.874 \times {10}^{-6} rad = 1.75 \times {10}^{-4}$$
As we know that,
$$\theta = \cfrac{d}{D}$$
$$\Rightarrow d = \theta \times D$$
$$\Rightarrow d = 1.75 \times {10}^{-4} \times 8.25 \times {10}^{11} = 1.44 \times {10}^{8} m = 1.44 \times {10}^{5} km$$
Hence the diameter of the jupiter is $$1.44 \times {10}^{5} km$$.
