Area=πr^2
find the area then divide by 8
we know that diameter=2radius or diameter/2=radius so
12=diameter
12/2=radius=6
subsitute
area=π(6)^2
area=36π
divide 36π by 8
36π/8=18π/4=9π/2π=4.5π
area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
The answer is 135 because the angle equals 180 by itself and 180 subtracted from 45 is 135 .. I hope this is helpful
The formula of a cirumference of a circle:
r - radius
We have r = 10. Substitute:
<h3>Answer: C = 20π</h3>
You meant pi, pi is a irrational number, but they use 3.14 for approximation, so that is your answer.
Hope this helped!
