The formula is used to find the diameter of circle is: d = \frac{C}{3.14}

The diameter of circle is 5.1 cm

<em><u>Solution:</u></em>

Given that,

Circumference (C) of a circle is 16 cm

<em><u>The formula for circumference of circle when diameter is given is:</u></em>

C = \pi d\\\\\pi \text{ is a constant equal to 3.14}\\\\C = 3.14d

<em><u>Rearrange the formula to get "d"</u></em>

Divide both sides by 3.14

d = \frac{C}{3.14}

The above formula is used to find the diameter of circle

Given that, circumeference = C = 16 cm

Substituting we get,

d = \frac{16}{3.14}\\\\d = 5.095 \approx 5.1

Thus diameter of circle is 5.1 cm

A club has 36 members. If each member donates 12 items for an auction, how many items will there be in the auction?
aivan3 [116]
I multiplied 36×12 because the keyword "Each" tells you that each person will donate 12 items. After I multiple, I got 432.

Answer: Yes, the answer is 40 quarters.


Step-by-step explanation:

1. You need to remember that 4 quarters make a dollar.

2. Keeping this on mind, you can make a Rule of three, as following: If there are 4 quarters in 1 dollar, how many quarters are in 10 dollars?

Then:

4 quarters-------1 dollar

          x---10 dollars

x=\frac{(10dollars)(4quarters)}{1dollar}\\x=40quarters

3. Therefore, there are 40 quarters in one roll.
