The circumference of a circle is always calculated by 2

R
So if R=2.5 m this circumference is 2*
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
*2.5 m
Which is 5

m (choice B)
Hope this helped!
To find missing lengths of sides
hope this helped have a nice day
This is in slope-intercept form, so you can think of it as being y=mx+b. Invert m (the slope) and flip its sign, and then substitute the x and y values in and solve for b. The answer is y=7/2x-20.
Answer:
208

Step-by-step explanation:
BE/BC=BD/BA
tHE TWO SIMILAR TRIANGLES ARE BED AND BC. tHE PROPORTION ABOVE REPRESENTS USE OF THE TWO SIMILAR TRIANGLES.
4/(4 + 10) = 5/(5+X) Cross Multiply
4(5+x) = 5(4+10)m
20 +4x=20 +50 subtract 20 from both sides
4x = 50 divide by 4
x =12.5
