Step-by-step explanation:
Diameter = 10 in
Radius = 5 in
Area of quarter circle = 1/4πr²
Area = 1/4 × 314/100 × 5 × 5
Area = 157/8 = 19.6 in²
Answer:
Let andre score be x points.
then Diego's score will be (x-9) points.
Noah's points=2(x-9) points
the equation is 2(x-9) = 10

2(x-9)/2 =. 10/2
x-9= 5
adding 9 both sides,
x-9+9= 5+9
x=14.
