Find the area of a circle with a circumference of 12.56 units.
Help me please

The area of the circle is 12.56 u²

Step-by-step explanation:

To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of circumference of a circle and we will clear the radius

c = circumference  = 12.56 u

r = radius

π = 3.14

c = 2π * r

r = c / 2π

we replace with the known values

r = 12.56 u / (2 * 3.14)

c = 2 u

The length of the radius is 2u

Now we calculate the area, we need to use the area formula of a circle:

a = area

r = radius = 2u

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (2u)²

a = 3.14 * 4u²

a = 12.56 u²

The area of the circle is 12.56 u²

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
