Answer:
The circumference of a circle is the distance around the entire circle, while arc length, s, is the distance <u>between</u> two points on the circle.
C = 2πr = 2π( <u>5</u><u> </u>) = 10π ≈ 31.4 units
3.14 is an approximation for π.
s = θ/360° (C)
mAB = 60°/360° ( 31.4)
= <u>1</u><u>/</u><u>6</u>(31.4) ≈5.2 units
C I'm pretty sure even though the real answer is 1979 so its d or c
Answer:
(11/2, -1)
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
We can find the slope between two points by using
m = (y2-y1)/(x2-x1)
= ( -9-6)/(-6 - -9)
=(-9-6)/( -6+9)
-15/3
-5
The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

Solving,

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

A little arithmetic shows that
