Answer:
78.5 or 78 1/2 units
Step-by-step explanation:
The formula for the area of a circle using diameter is 1/4*pi.*d to the second power. Plug it in, and you get 78.5 or 78 1/2 units.
We can start with the whole of 135, and find out 10% of that.
135/10 or 135 divided by 10= 13.5
This means that 1/10 of it is equal to 13.5, and that’s 10%. To find 20%, you want to do 13.5 x 2, and this will get you 27.
The answer is 27.
