Answer: Choice B) multiply the radius by 2, then by 3.14
The formula is
C = 2*pi*r
which you can rearrange to get C = 2*r*pi, showing you multiply 2 and the radius r, then multiply by pi = 3.14 which is approximate
A similar related formula is
C = pi*d
where d is the diameter. Note that d = 2*r, so we can replace d with 2r to get the first formula back again.
the circumference is the distance or perimeter around the circle

Answer:
240 cm
Step-by-step explanation:
8x=12(x-10)
8x = 12x -120
120 = 4x
30 = x
I'll let <em>h</em> = <em>ax</em>, so the limit is
i.e. the derivative of .
Expand the numerator to see several terms that get eliminated:
So we have
Since <em>h</em> ≠ 0 (because it is approaching 0 but never actually reaching 0), we can cancel the factor of <em>h</em> in both numerator and denominator, then plug in <em>h</em> = 0:
