The formula for finding circumference is C=2*pi*r. So C is the circumference that you are trying to find. Pi is 3.14. And r is the radius. Now, it does not tell you directly what the radius is, but the diameter of a circle is basically how far across is it. So in this case, 14. The radius of a circle is half of it's diameter, so half of 14 is 7. So, multiply 2*3.14*7, to get the circumference. You get 43.96.
The lengths of the three line segments after dilation is 
, 
and 
Explanation:
Given that the length of three line segments are PQ = 2 cm, AB = 1.5 cm and MN = 3 cm
Also, given that the dilation with a scale factor of 2 is applied to the three line segments.
We need to determine the length of line segments P'Q', A'B' and M'N'
Dilation means the transformation of the same shape with different size.
Since, it is given that the dilation with a scale factor of 2, we shall multiply each of the line segments with 2.
Thus, we have,
Thus, the lengths of the three line segments after dilation is , and
Answer: (3x + 11y)^2
Demonstration:
The polynomial is a perfect square trinomial, because:
1) √ [9x^2] = 3x
2) √121y^2] = 11y
3) 66xy = 2 *(3x)(11y)
Then it is factored as a square binomial, being the factored expression:
[ 3x + 11y]^2
Now you can verify working backwar, i.e expanding the parenthesis.
Remember that the expansion of a square binomial is:
- square of the first term => (3x)^2 = 9x^2
- double product of first term times second term =>2 (3x)(11y) = 66xy
- square of the second term => (11y)^2 = 121y^2
=> [3x + 11y]^2 = 9x^2 + 66xy + 121y^2, which is the original polynomial.
