Can someone help me with these 2 polygons and how to figure out a circumference
1 answer:
The circumference of a circle is found by using the equation: C= 2 x PI x r
Both circles have r = 1
Circumference = 2x 3.14 x 1 = 6.28.
Diameter is 2 times the radius= 2x1= 2
The ratio of the circumference to the diameter = 6.28 / 2 = 3.14 which is the value of PI

19.4 added to 24.2 would be 43.6
ANSWER: 43.6
C = -840
Isolate C by subtracting 900 on both sides:
C = 60-900
Which then gives u C = -840
Answer:
The answer in this proble is 269
Answer:
-7-y1=-4(2-x1)
Step-by-step explanation:
Point slope form is like this: y-y1=m(x-x1) where y is the y value, x is the x value, and m is the slope. You plug the values in.
