if two circles have circumference of 12 pi inches and 18 pi inches,find the ratio between their radii

djverab [1.8K]

The formula for the circumference is:
$2\pi r$
So to find first radius:
$2\pi r = 12\pi \\ \\ \pi r = 6\pi \\ \\ r = 6$
Second radius:
$2\pi r = 18\pi \\ \\ \pi r = 9\pi \\ \\ r = 9$
The ratio between them is:
$\frac{6}{9} = \frac{2}{3} = 0.66667$

Answer:

$\boxed{x = 7}$

Step-by-step explanation:

75 = 11x-2 <u><em>(Corresponding angles are equal)</em></u>

11x -2 = 75

Adding 2 to both sides

11x = 75+2

11x = 77

Dividing both sides by 11

x = 7

Answer:

$\frac{55}{14}$

Step-by-step explanation:

First, we convert the mixed numbers into improper fractions: $1\frac{3}{7} =\frac{10}{7}$ , and $2\frac{3}{4}=\frac{11}{4}$ . Now, we multiply the fraction using the multiplication rule, $\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}$ : $\frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}$ .
