Full circle
Circumference = 2*pi * r
Circumference = pi * d
Area = pi r * r = pi * r^2
Area = pi d^2 / 4
Half circle
Circumference = pi * r
Circumference = pi * r / 2
Area = pi r^2 / 2
Area = pi d^2/8
The answer depends on what you are looking for and what you are given. But those are the only common formulas I can think of at the moment.

Answer:
5.5lb of strawberries cost $10.78
Step-by-step explanation:
We can use ratios to solve this problem.
lb : $$$
0.5 : 0.98
5 : 9.8
5.5 : 10.78
5.5lb of strawberries cost $10.78
You can also divide 5.5 by 0.5 (pounds) and multiply the quotient by how much a 0.5 pound of strawberries cost.
