Answer:
380.13 m
Step-by-step explanation:
You first need to write down the Area formula for a circle which is A=pi x radius^2 .
So 11^2 x 3.1415...
121 x 3.1415... = 380.13 m
97.50 / 8.75 is 5.40 so yeah thats the awnser and stuff
85/15 is 5 2/3
so, to find 85% with 15%, you would multiply 12 (also 15%) by 5 2/3.
12*5 2/3=68.
you could also find it using the 1% method:
1% of 15 is .15.
.15*85=68.
Hope this helps!
