Answer:

[tex]use \: this \: formula \\ circumference = dimeter \times 3.14 = 2 \times radius \times 3.14 \\ \\ area = 0.25 \times {diameter}^{2} \times 3.14 = {radius}^{2} \times 3.14[/tex]
I think I can’t help you but
Did you write the black text because it makes no sense you put the equitation and then the other the next box
The formula for circumference is pi diameter as seen below.
And then you find area by doing 3.14 times radius^2

Here is the answers for circumference going across
43.96, 69.08, 40.82, 28.26, 57.78

Next is area going across
153.86, 379.94, 132.67, 63.59, 265.77

Let me give you an example of how I did those
The ones with half a line are radius and diameter would be times 2 that
In order to find circumference, for the second one I did 11 times 2 (22) and then 22 times 3.14 (pi)
And for the area I did the radius already given
3.14 times 11^2
You have to square the radius and times it by pi
On the other questions if diameter, the whole line across the circle, is given then divide it by 2 to get radius.
Hope that helps!
