# How can you find the Sun's diameter based on a tree shadow?

##### 1 Answer

I will divide the answer in steps:

1: Go beneath a tree where you can find a circular shadow of leaves on the ground. These shadows are called as ** Sunballs**.

2: Measure the diameter of the Sunball.

3: Measure the distance from the Sunball to the leave from where this shadow is forming.

4: ** The ratio of Diameter of Sunball (d) to Distance of the Sunball (h)** will give you the

**because this whole thing is same as**

*diameter of the sun (D)*

*the diameter of the sun to the distance of the sun to the leaves.*

5: Just convert the values to

You can also perform this experiment by poking a hole in cardboard and performing all the above steps.
