Complete the ratio table.

Mathematics
1 answer:
rosijanka [135]3 years ago
5 0

Answer:

63, 946

Step-by-step explanation:

The circumference of a circle can be found using the equation 2rpi.

I like to think of this as Dpi with D being the diameter since 2r is equal to D.

42 times 3.14 is roughly 132. x times 3.14 is 198, meaning 198 divided by 3.14 is roughly 63. 301 times 3.14 is roughly 946.

3 is 12% of (unknown number)
12% × x = 3
or 12 / 100 × x = 3
Multiplying both sides by 100 and dividing both sides by 12,
we have x = 3 × (100/12)
x = 25
