Two angles that added together equal 90 degrees
To find the midpoint of a line use the midpoint formula which is M = (x1+x2/2 , y1 +y2/2) After plugging in the coordinates for your variables you should get (-1+5/2, -1+2/2) This simplifies to (2, 1/2) which is the coordinates for the middle point of the base XY.
62.5%
5/8 = 0.625 then multiply by 100% to get in terms of percent of 62.5%
Answer:
6π
Step-by-step explanation:
You have to use the formula for the circumference of a circe:
Circumference = π(diameter)
However, you do not have the diameter, you have the radius.
Diameter = radius * 2
Diameter = 3 * 2
D = 6
Now you can substitute this value back into the Circumference formula:
C = πd
C = 6π
