The tenths place is right after the decimal point. So, 3160.9903 can be 3160.9.
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.

#SPJ1
An ordered pair of the inverse of f(x)D, (1.2)
Answer:
Step-by-step explanation:
An adult ticket costs $2 more than a child ticket
Let x and (x + $2)represent the cost of the child and adult ticket respectively
2(x+ $2) + 3x = $34
now solving for x
2x+ $4 + 3x = $34
5x = $30
x = $6 , the cost of the child ticket.
the cost of adult ticket $6+2=$8
In this problem, we are given the equations of the two sides
of a rhombus.
Equation 1 is 4 x – 10
Equation 2 is 2 x + 20
Since the given shape is a rhombus, therefore the two sides
have equal sides. Hence, we can simply equate equation 1 and equation 2:
4 x – 10 = 2 x + 20
2 x = 30
x = 15
Therefore the answer is:
A. 15
