(45/360)2πr=9π/4

Mathematics
1 answer:
Lyrx [107]3 years ago
7 0

Answer:

r=9

Step-by-step explanation:

45/360=1/8

1/8*2=2/8

2/8=1/4

1/4*pi*r=(9pi)/4

Divide both sides by 1/4 (the fours cancel each other out)

Pi*r=9*pi

Pi cancels each other out

R=9

Hope this helps

10^6 = ----------
                 x
                                100 m
Solving for x,  x = ------------- = 10^(-4) m, or [10^(-1)] * [10^(-3))]

this comes out to one tenth of 1 millimeter.
