The formula is 2 (pi)r
The diameter is a 27.4 which means the radius is half of that or 13.7.
So 2 (pi)r equals 27.4 (pi)
That should be your answer
Answer:
------------------------------------
Add up the corresponding elements
Row1,Column1: 6.1+(-7.2) = -1.1
Row1,Column2: 1.9+7.6 = 9.5
Row2,Column1: -7.5+1.8 = -5.7
Row2,Column2: 2.2+(-1.4) = 0.8
Row3,Column1: 3.8+2.3 = 6.1
Row3,Column2: -1.4+2.1 = 0.7
So that's why the answer is
Answer:
b) (-6, 0)
Step-by-step explanation:
The quickest method to use is to put "0" in for <em>y</em><em>,</em><em> </em>then figure out which term for <em>x</em> would make the equation authentic, or genuine.
Answer:D
Step-by-step explanation:
2x + 3y = 12
-2x -2x
3y = -2x + 12
/3 /3 /3
Y = -2/3x + 4
<u>1) Rewrite it in the form a^2-2ab+b^2, where a=11m and b=9</u>
(11m)^2-2(11m)(9)+9^2
<u>2) Use Square of Difference: (a-b)^2=a^2-2ab+b^2</u>
(11m-9)^2
<u>Your answer is (11m-9)^2</u>
