Find the radius of a circle in which the central angle of (pie /4 ) radian determines a sector with an area of 86m^2
1 answer:
Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80

Answer: 128
Step-by-step explanation:
Let the number = X
4x + 8x = 36
Simplify:
12x = 36
Divide both sides by 12:
x = 3
The number is 3
