Answer:
18.84 estimated, 6π exactly
Step-by-step explanation:
Hi!
<u>The formula for finding the circumference of a circle is 2πr:</u>
In that case, all we need to do <em>first </em>is to divide the diameter by 2, so we can substitute that into the equation.
6 ÷ 2 = 3
So we have 2π × 3 to solve.
2π × 3 = 6π
We can estimate the circumference by multiplying by 3.14.
6 × 3.14 = 18.84
(actually multiplying by π gives 18.849... which is pretty close!)
Thus, the circumference is
.
Hope this helps!
Answer:
Positive

-465+465
= 465-465
=0
Zero is positive.
Answer:
2x+12
Step-by-step explanation:
2x+3(x-2)-3(x-6)
2x+3x-6-3x+18
2x-6+18
2x+12
It would be 60. He sold his painting for 50 which was 10 less that the original price. So 50+10=60
Answer: 120 grams.
Step-by-step explanation:
Let x be the amount of sugar syrup made by 5% sugar syrup using 6g sugar.
Also, 5% =0.05
Therefore, 5% sugar syrup =5% of x = 0.05x
According to the question, we have
![0.05x=6\\\text{Divide 0.05 on the both sides we get}\\\Rightarrow\ x=\frac{6}{0.05}\\\Rightarrow\ x=\frac{600}{5}\\\Rightarrow\ x=120](https://tex.z-dn.net/?f=0.05x%3D6%5C%5C%5Ctext%7BDivide%200.05%20on%20the%20both%20sides%20we%20get%7D%5C%5C%5CRightarrow%5C%20x%3D%5Cfrac%7B6%7D%7B0.05%7D%5C%5C%5CRightarrow%5C%20x%3D%5Cfrac%7B600%7D%7B5%7D%5C%5C%5CRightarrow%5C%20x%3D120)
Hence, 120 grams sugar syrup is made by 5% sugar syrup of 6g sugar.
