To find the circumference of a circle you multiply pi (3.14) by the diameter ad to find the area you multiply pi (3.14) times the radius squared
Since the circumference is 31.4 divide that by pi to find the diameter which is 10
The radius of a circle is half of the diameter, so for this circle the radius is 10 / 2 = 5
Take the radius and square it : 5^2 = 25
Then multiply the squared radius by pi (3.14) to find the are : 25 * 3.14 = 78.5
So the area of this circle is 78.5 centimeters squared

The easiest way to find out is with a calculator.
0.125 = 1/8=1÷8
Here is an example on how you should do your multiplication. The website should give you your answer to any multiplication.
Hope this helps love!! <3
because the symbol is a less than sign < the blue area needs to be below the red line and does not include the solution to Y ( if it included Y it would be a ≤ symbol.
When the solution isn't included, it is a dashed line.
so the answer would be D
Well, the perimeter is 35+50+35+50, or 170.
the lenght as we know, is the longer side, or 50,
so their ratio is
