Pie, or circle graph
These graphs help us compare the different parts of an entire element and see the part's contribution.
Answer:Half of the diameter so d/2 or distance from the midpoint to the circle border
Step-by-step explanation:c=2pie•r^2
Answer:
5+2.50m <=20
Step-by-step explanation:
<= -- means less than or equal to
Answer:
Approximately mMK is 53 degrees
Step-by-step explanation:
Here, we want to find the length of MK
As we can see, we have a right triangle at LNK
so
let us find the angle at L first
9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L
so the trigonometric identity that connects adjacent to the hypotenuse is the cosine
It is the ratio of the adjacent to the hypotenuse
So;
cos L = 9/15
L = arc cos (9/15)
L = 53.13 degree
Approximately, L = 53 degrees
so now, we want to get the arc length MK
We are to use the angle-arc relationship here
Using this; arc length MK is equal to the measure of L at the center which is 53 degrees
Answer:
A: 180°, semi circle
Step-by-step explanation:
We are told that MK and HL are the diameters.
By Inspection, it is clear that MHK will be a semi circle.
The angle of that chord will be 180° since sum of angles on a straight line is 180°.
Answer is option A
