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.

What is the answer to this decimal problem 0.32÷n=0.032

11111nata11111 [884]

10 because you know that the decimal moves one to the left if you are dividing by ten and one to the right if you are multiplying by ten.

Check your work. 0.32 divided by 10 is 0.032

Step-by-step explanation:

The area is calculated by multplying radius (half of diameter) by itself and then with number pi

the area for this circle is given as
