The area of a sector of a circles is calculated by the equation A = πr^2 (theta/360). From the data of the sector, we determine the radius of the circle. THen, we can calculate for the area of the circle.
16.4π = πr^2 (72/360)
r = 9.06
Area of circle = πr^2
Area of circle = π(9.06)^2
Area of circle = 82π

Answer:
Width: 7 Length: 10
Step-by-step explanation:
Width: x
length: 2x-4
Area: 70 meters squared
(2x-4)x=70
2x^2-4x=70
2x^2-4x-70=0
2(x^2-2x-35)=0
(x-7)(x+5)=0
x cannot be negative so x=7
