Answer:

The diameter is equal to the circumference divided by the number pi

Step-by-step explanation:

we know that

$C=\pi D$

where

D is the diameter

we have

$D=6\ ft$

substitute

$C=\pi (6)$

$C=6\pi\ ft$

Divide the diameter by the circumference

$\frac{D}{C}=\frac{6}{6\pi}$

$\frac{D}{C}=\frac{1}{\pi}$

$D=\frac{C}{\pi}$

The diameter is equal to the circumference divided by the number pi

Write the fraction 1/8 as a percent rounded to the nearest hundredth of a percent where necessary

Irina-Kira [14]

To determine the answer to this you would divide the numerator by the denominator in an equation. The answer to that equation is 0.125. When converting a decimal to a percentage, you shift the decimal point over two places. Thus the percentage is 12.5% and it is unnecessary to round the result to the nearest hundredth of a percent. The answer is 12.5%.
