The measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a length of an arc of a circle of radius 7 is approximately 10.99 cm.
The radius r = 7 cm
The arc length l = 10.99 cm
We know,
l = rθ
θ is the central angle.
θ = l/r = 10.99/7 = 1.57 radians
To convert 1.57 radians into the degree multiply it by 180/π
θ = 89.95 degree
Thus, the measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.

Because -
2 x 12=12
2 x 13 = 36
2 x 42 = 84
Answer:
y=11
Step-by-step explanation:
Solve the system by substitution by setting the equations equal to each other.
y = 5x+6
y = x+10
It becomes 5x+6 = x+10. Solve for x using inverse operations.
5x+6 = x+10
4x+6 = 10
4x = 4
x=1
Substitute x=1 into one equation to find y.
y = x+10
y = 1 +10
y=11
