Answer:
Radius: 8
Circumference: 50.27
πr^2 = Area of circle
201.06 = πr^2
divide by pi
201.06 / π = 63.9993857161 = 64
64 = r^2
Square root both sides to get radius.
= 8
r = 8
Circumference = π x diameter
Diameter = 2 x radius
Circumference = π x 16 = 50.2654824574 = 50.27
The last answer, (40 pieces of paper)
58 degrees
Explanation
If you have a triangle with the angle measures of abc as 58 degrees, 102 degrees and 20 degrees you can multiply them in order of abc so 58 degrees is angle a, 102 degrees is angle b and 20 degrees is angle c. Then you just put in angle a for d which would be 58 degrees and angle e for b 102 degrees and angle f for c which would be 20 degrees
Answer:
Is not the answer but is how to do it. Sorry
Step-by-step explanation:
you got the value of a=2
use the formula
S=n/2 [2a+(n-1)d] then calculate d from here..
put it in t=a+(n-1)d
Answer:
y = 1/2x + 2
Step-by-step explanation:
slope = 1/2
3 = 1/2(2) + b
2 = b
y = 1/2x + 2
