This is what I would do.
The general formula for the circumference of a circle is
where r is the length of the radius of the circle. Simply use the formula to find r so that you can draw the circle:
Now, draw a circle with a radius of 1.571 inches. This number has been rounded up to 3 significant figure. Hope this helps!
1. We are given:
The only a which squared gives you 64 is 8. The perimeter of an 8 by 8 square will be 32. Half of that is 16. Now, let's see what we can do. We can set up:
Obviously, each side length has to be 4. So, the area of this square will be 16 units².
2. Let n equal her son's age. So, her age right now will be (S = her age):
1 year ago it was:
We have 2 equations, let's substitute. We can rewrite this as:
Solve for n:
We know the value of n, which is her son's age. So, her son is 1/15 of a year old or about 24 days old.
