Step-by-step explanation:
always write what you know
circumference
U = 2 x pi x r
r = d/2
U = 39.25
rearrange and solve for r
U / (2 x pi) = r
solve for diameter
2r = d
Answer:
5.1
Step-by-step explanation:
Add 4.3 to 0.8
N = 80 degrees
P = 95 degrees
M = 95 degrees
N and 100 form a 180 degree angle and thus you can solve using subtraction.
P is the same angle as the angle opposite of it.
You can get M by subtracting the other 3 angles from 360.
