If you were trying to get the area of a whole circle, you would use
Area = pi r^2
You have to modify the formula to show that just part of the circle has an area that you are interested in.
The new formula is
Area = (theta/360) pi r^2
Givens
r = 30 cm
theta = 100
Solution
Area = (100 / 360) * pi * r^2 Substitute the givens into this formula
Area = (5 / 18) * pi * 3^2 Expand
Area = (5 / 18) * pi * 9 Cancel 9 into 18
Area = 5/2 * pi
Area = 2.5 * pi
Step-by-step explanation:
let, the 3rd game score be x
then 1st game score becomes = x+10
2nd game score becomes = x-5
total=275
x+x+10+x-5=275
3x+5=275
x= 270÷3
x=90
1st game score becomes = x+10= 90+10= 100
