Area of a circle = pi x radius squared
Radius of a circle is from any point on the circumference to the centre
Diameter is the distance between two points on the circumference with the line crossing the centre
So radius is half of the diameter...
In this example radius is therefore 9mm (half of 18mm)
Square this... 9x9=81
So in terms of pi the answer is 81pi
To get the full answer you would just times pi (3.14) by 81 =254.34

Julie gives 7 pieces of candy to each of her friends. If Julie gives all of her candy away, which amount of candy could have bee
True [87]
To find the answer to this problem, you just need to figure out which total amount of candy is divisible by 7.

161/7=23
<span>162/7=23.1428571429
</span>145/7=<span>20.7142857143
128/7=</span><span>18.2857142857

Obviously, Julie cannot give a fraction of an amount of candy to someone.  So that rules out that she had 162, 145, or 128 pieces of candy.  

The only amount of candies that Julie could have that is divisible by 7 is 161 candies, which means that 161 is your answer.</span>
