Circumference of the circle is given as = 220 feet
We have to find the diameter.
Circumference is found as = 2 * PI * r
r=35.03
Diameter is 2*radius
Diameter = 
= 70.06
Hence, diameter of the circle is 70.06 feet.
6, 2, -2 i could be wrong :/
They are because 2.7 squared + 3.6 squared = 4.5 squared (=20.25)
Pythagoras Theorem is that a squared + b squared = c squared
So the 2 smallest numbers squared will equal the larger one squared if it is a pythagoreom triple
She subtracted 6 from a certain number and then divided the result by 3, giving her 35.
(x - 6) / 3 = 35
x - 6 = 35*3
x - 6 = 105
x = 105 + 6
x = 111
so she should have subtracted 3, then divided by 6
(111 - 3) / 6 = 108/6 = 18 <===
First, let's prove that triangle ABC and AFG are similar.
Line segment FG and BC are parallel to each other, that's a given.
With this information, we can state that these sides are similar to each other since you can transform BC on to FG using only rigid transformations and dilations.
Another thing is that both of these triangles share angle A, that's a given. Therefore, using the SA similar theorem, we can conclude that these triangles are similar.
Now that we know that triangle ABC and AFG are similar we may start going to the answer box.
We can eliminate the first three answer choices for having sides we cannot make full conclusions due to limited knowledge.
The only answer remaining is the fourth choice.
