Answer:
<em>Circumference:</em> 18.84 cm
<em>Area:</em> 28.26 cm^2 (exponent 2)
Step-by-step explanation:
Circumference = 2(pi)r
The diameter is 6. Means the radius is 3 (half of 6)
pi = 3.14
2(3.14) x 3 = 18.84
Circumference is 18.84 cm.
Area of a circle = (pi)r^2
(3.14)(3)^2 = 28.26 cm^2 (exponent 2)
Answer:
5
Step-by-step explanation:
60÷6 is 10
54÷6 is 9
30÷6 is 5
have you tried 42 because it's a 90 degree triangle and 30+18+42 equals 90
N% x 1.60 = 6 (I turned it from English to math)
Can't move n% back two places to make it a decimal so I will move the number I am multiplying by n% back two places instead.
Here is a sample to show you why it works. .34 x 57 = 34 x .57
So
.016n = 6 (.016 is 1.60 decimal moved back two places)
Now divide both sides by .016
<u>.016</u>n = <u>6
</u><u />.016 .016 n = 375%
Why is the percent over 100% you might ask?
What % of 1.60 is 1.60 (Answer - all of it or 100%)
So What % of 1.60 is 6 - the number 6 being much bigger than 1.60, it is not surprising that the percent is more than 100.
What % of 1.60 is 1.60 - 100%
What % of 1.60 is 3.20 - 200% (notice that 3.20 is twice 1.60)
What % of 1.6 is 4.80 - 300% (notice that 4.80 is three times 1.60)
What % of 1.6 is 6.40 - 400% (notice that 6.40 is four times 1.60)
6 (the number in the problem) is just a bit less than 6.40 so 375% makes a lot a sense.
Hope you found this helpful.
