Answer:
The answer is
.
Step-by-step explanation:
Given:
77.5%.
Now, to write as a fraction or mixed number in simplest form.
77.5%
So, we divide by 10 by removing decimal as decimal is at tenth place.
= 
So, simplifying it:

Now, we change into mixed fraction:

Therefore, the answer is
.
20 thousands would be 200 hundreds
Area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 * 5 * 8 = 20 cm^2 and there are 4 sides
So the surface area of while pyramid = 4 * 20 + 25 = 105 cm^2
Volume of the cone = (1/3) pi r^2 h
= (1/3) pi * 5^2 * 8
= 209.44 ft^2
