Answer: 423.11 m^2
Step by step explanation:
Area of a circle formula pi*r^2
First solve the area of the big circle
3.14*21^2=1384.74 m^2
Now find the are of the smaller circle
r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2
Now we can minus the small area off the big area to get the shaded area.
1384.74-961.63=423.11 m^2
So the area of the shaded region is 423.11 m^2
Answer:
$837.25
Step-by-step explanation:
100%-> $985
1%->$9.85
15%->$9.85×15=$147.75
85%->$985-$147.75=$837.25
All you have to do is subtract 3/8 from 7 which would give you 9 and 1/3
