Question

The diameter of sun is approximately 20^9 meters. A modal of the sun has diameter of 20^-1 meters. How many models would fit across the diameter of the sun?

Answer 1

To find how many models will fit, just divide the diameter of the sun by the diameter of the model,

Let the number of models be x

$x = \frac{ {20}^{9} }{ {20}^{ - 1} }$

$x = {20}^{9 - ( - 1)}$

$x = {20}^{9 + 1}$

$x = {20}^{10}$

Therefore, 20^10 models will fit inside the sun
