Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm
Answer: No, the ratios 11/15 and 1/6 do not form a proportion.
Explanation: Proportion says that two ratios (or fractions) are equal.
Example:
Proportion 1/3 : 2/6
So 1-out-of-3 is equal to 2-out-of-6
The ratios are the same, so they are in proportion.
If I multiplied 1 by 11 and then 6 by 11, I would get 11/66, therefore 11/15 and 1/6 do not form a proportion.
