What is circle ?
A circle is a spherical shape without boundaries or edges.
A circle is a closed, curved object with two dimensions in geometry.
Consider two small arcs AB and CD of two circles of radii x and y units, both of which make an angle of measure θ at the centers P and Q respectively.
For smaller values of θ, the arc length AB is almost equal to the length of the line segment 
. Similarly, arc CD ≅ 
.
Using the SAS rule of triangle similarity, we can say that APB and CQD are similar triangles because their angles are the same and their ratios are AP: PB = CQ: QD = 1: 1. So, it stands to reason that AB: AP = CD: CQ.
Circumference = 
diameter or circumference = 2 radius if this constant equals some value.
So it was proved.

Answer:
Tooth A
Step-by-step explanation:
Since the larger tooth has to be displayed, knowing that no matter how many zeros you add to the end of a decimal, the value of it will stay the same. 0.23 is 1 digit short that 0.195, so if you just add a 0 to 0.23, it make both of them have a digit in the thousandths place. Now it's easier to solve, 0.230>0.195.
Tooth A should be displayed.
Answer:
y = -5/2x + 10
Step-by-step explanation:
Step one: Add -5x to both sides.
5x + 2y + -5x = 20 + -5x
2y = -5x + 20
Step two: Divide both sides by two.
2y/2 = -5x + 20/ 2
y = -5/2x + 10
Hope my answer help.
Answer:A 12 cm
Step-by-step explanation:
because 5 rounds 2 to 3 and 3 divdied by 12 is 4 sinbce it is equal.
Answer:
p=30 cm
Step-by-step explanation:
so the formula there is to find the perimeter of the rectangle so we are going to use that
