Answer:

Step-by-step explanation:
IT IS CONVENTIONAL to let the letter s symbolize the length of an arc, which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally, "stretches under."
Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π.
π = C
D .
Since D = 2r, then
π = C
2r
or,
C
r = 2π .
arc lengthThat ratio -- 2π -- of the circumference of a circle to the radius, is called the radian measure of 1 revolution, which are four right angles at the center. The circumference subtends those four right angles.
arc length
Radian measure of θ = s
r
Thus the radian measure is based on ratios -- numbers -- that are actually found in the circle. The radian measure is a real number that indicates the ratio of a curved line to a straight, of an arc to the radius. For, the ratio of s to r does determine a unique central angle θ.
Answer:
26=y
Step-by-step explanation:
-7*-4= 28
28-2=26
The first hexagon: 2, 2, 3, 4, 6, 7
The second hexagon: 3, 3, a, b, c, d
The hexagons are similar. Therefore the sides are in proportion.
<em>multiply both sides by 3</em>
<em>multiply both sides by 4</em>
<em>multiply both sides by 6</em>
<em>multiply both sides by 7</em>
The perimeter:
Answer: y = 2x - 4
Step-by-step explanation:
Gradient => (2 - (-2))/(3 - 1) = 4/2 = 2
so, equation is y = 2x + C
Using (3, 2) we have: 2 = 2(3) + C
Hence, C = -4
Therefore, y = 2x - 4
