The formula for the circumference of a circle is C = 2r. What is one-fourth of the circumference of a circle that measures 12 ce

Harman [31]

The formula of a circumference is:

$C=2\pi r$

r - radius

or

$C=d\pi$

d - diameter

We have d = 12cm. Substitute:

$C=12\pi\ cm$

One-fourth of the circumference:

$\dfrac{1}{4}C=\dfrac{1}{4}\cdot12\pi=3\pi\ cm\approx3\cdot3.14=9.42\ cm$

<h3>Answer: 9.42 cm.</h3>

I need with these problems

ch4aika [34]

Answer:

1. $\frac{5}{6}$

3. $\frac{7}{0}$ (undefined slope)

5. $-\frac{7}{4}$

7. $24$

Step-by-step explanation:

slope (m)

rate of change (r)

1. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{8-3}{13-7} =\frac{5}{6}$

3. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{4-(-3)}{9-9} =\frac{7}{0}$ (undefined slope)

5. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{-1-6}{0-(-4)} =\frac{-7}{4}=-\frac{7}{4}$

7. r = $\frac{f(b)-f(a)}{b-a}=\frac{24-0}{1-0}=\frac{24}{1}=24$

Hope this helps!
