Fine the area of the circle:
Area of a circle = pi x r ^2
Area of the circle = 3.14 x 4^2 = 50.24 square cm 
Find the area of the triangle:
Area of triangle = 1/2 x base x height
Area =1/2 x 8 x 4 = 16 square cm
Find the area of the white part by subtracting the area of the triangle from the circle:
50.24 - 16 = 34.24 square cm.
The probability of landing in white is the area of white/ area of circle:
34.24/50.24 = 0.682 
Multiply by 100 to get percent:
0.682 x 100 = 68.2%

The observatory telescope has 22 times the magnifying power compared to the small telescope.
Data;
- small telescope = 150 times
- large telescope = 3300
<h3>Division of Numbers</h3>
To solve this question, we have to divide the large telescope by the small telescope to calculate it's magnifying power.
 
The magnification of the observatory telescope is 22 times greater or larger than the small telescope.
