Which is the area of a circle with a circumference of 37.68 units? (use 3.14 for pi)
its 113.04 square units
idk where im soposed start and soposed to square it plz help
Right!
To find the area of a circle, you need to use the formula A = πr^2, where A represents the area, π represents the mathematical constant pi, and r represents the radius of the circle.
First, we need to find the radius of the circle using the given circumference. The circumference of a circle is calculated using the formula C = 2πr, where C represents the circumference and r represents the radius.
In this case, we are given the circumference C = 37.68 units. We can rearrange the formula to solve for the radius:
C = 2πr
37.68 = 2 * 3.14 * r
Now we can solve for r.
Divide both sides of the equation by 2π:
37.68 / (2 * 3.14) = r
r ≈ 6 units
Now that we have the radius, we can substitute it into the area formula to find the area:
A = πr^2
A = 3.14 * (6)^2
A = 3.14 * 36
A ≈ 113.04 square units
Therefore, the area of the circle with a circumference of 37.68 units is approximately 113.04 square units.
