Answer: No it's not possible to form a triangle
Why not? Because the shorter sides 2 ft and 3 ft don't add to a result longer than 7 ft
2+3 = 5
For a triangle to be possible, the sum of any two sides must be larger than the third side. Refer to the triangle inequality theorem.
Whenever a number is followed by percent, you can turn it into a fraction by simply moving the decimal places two places to the left:
90.0 % becomes .90
As a fraction, this is 90 over 100. To reduce it to its simplest form, divide by 10:
9/10
It's not a proper square root, but you're looking for a number between 25 and 26 (<span>25.6515106768)</span>

Question from Amanda, a parent:
what is the area of a circle with a circumference of 3000 metres?
Amanda,
The area of a circle is given by the formula A = π r2, where A is the area and r is the radius. The circumference of a circle is C = 2 π r.
If we "solve for r" in the second equation, we have r = C / (2 π ). Now we use this to replace r in the first equation: A = π [ C / (2 π ) ]2.
When we simplify this, we get A = C2 / (4 π).
Now you can put your value of C into this equation and find A. Remember, π is about 3.1416.
