A=pie×radius squared is the area formula of a circle. The circumference formula or a circle is C=pie×diameter. 615.75=(3.14)(radius) squared. Divide both sides by the 3.14. What ever 615.75 divided by 3.14 is-is radius squared. The square root is your radius. The radius is half the diameter, so double what you have right now as the radius to get the diameter. Now since C=pie×diameter, your circumference is your pie×your diameter. Whatever your answer is-is your circumference.

Total marbles = 7 + 12 + 8 + 5 = 32
Green marbles = 8
Yellow marbles = 12
P(green ,then yellow) = (8/32)(12/32) = 3/32
Answer: The probability is 3/32
The probability of drawing a two and another 2 is 1/72
<h3>What is probability?</h3>
Probability is the likelihood or chance that an event will occur
- Since the total number in the board game is 9, hence the probability of drawing a 2 will be 1/9
- The probability of drawing the second 2 will be 1/8
- Pr(drawing a 2, then drawing another 2) = 1/9 * 1/8
Pr(drawing a 2, then drawing another 2) = 1/72
Hence the probability of drawing a two and another 2 is 1/72

<u>Answer:
</u>
The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.
<u>
Solution:
</u>
Given that current population of city is 27900.
Also, population of a city has decreased by 38% since it was last measured.
Let assume that population of city when it was last measured = x
Decreased of 38% means x-38% of x . we can write this as,



So current population is 
Equating above expression to the given value of current population, we get


x=45000
Hence previous population of city was 45000.
