The length of an arc is the fraction of its circumference based on the given intercepted angle. This is given by the equation,
L (arc) = (Angle / 360) x 2πr
Substituting the known values,
L (arc) = (40 / 360) x 2π(8 inch) = 16π/9 inch
Thus, the length of the arc is approximately equal to 5.585 inches.
The area of a circle in terms of the circle's radius
is
Differentiating both sides with respect to
, you get
Answer:
That is the system.
y = x - 4
y = 4x - 10
If you are looking for the solution then use the method of substitution or the method of elimination.
