The perimeter of the quarter circle is the length of the straight edges plus the length of the curved edge. perimeter = r + r + In the same way, we can find the perimeter of any sector. Let us have a sector, and let the angle between the radii be xo. There are 360o in a circle.

Perimeter of sector = 2 radius + (radius × central angle)

Carlos evaluated 20 - (2x6) + 8 ÷4 and got 29. Is his answer correct? If not, explain what Carlos did wrong and find the correct

natima [27]

20-(2x6) +8 divided by 4
2 times 6 = 12
8/4 = 2
20-12+2
It would be 14 not 29

What is the slope of (17,-15) (11,-13)

Korolek [52]

Answer:

The slope of this line is -1/2

Step-by-step explanation:

To find the slope of any equation, we need to use the slope formula.

m (slope) = (y2 - y1)/(x2 - x1)

m = (-13 - -15)/(11 - 17)

m = (-12 + 15)/(11 - 17)

m = 3/-6

m = -1/2
