Answer
The circumference of a circle is 25π in. What is the area, in square inches
Answer
The circumference of a circle is 19π m. What is the area, in square meters
Answered by GPT 3.5
To find the area of a circle, we use the formula A = πr^2, where r is the radius of the circle.

Since the circumference of the circle is 20π cm, we can find the radius by dividing the circumference by 2π:

Radius = Circumference / (2π) = 20π / (2π) = 10 cm

Now we can calculate the area:

Area = π * (10)^2 = 100π cm^2

Therefore, the area of the circle is 100π square centimeters.

Since the circumference of the circle is 25π in, we can find the radius by dividing the circumference by 2π:

Radius = Circumference / (2π) = 25π / (2π) = 12.5 in

Now we can calculate the area:

Area = π * (12.5)^2 = π * 156.25 = 156.25π in^2

Therefore, the area of the circle is 156.25π square inches.

Given that the circumference of the circle is 19π m, we can find the radius by dividing the circumference by 2π:

Radius = Circumference / (2π) = 19π / (2π) = 9.5 m

Now we can calculate the area:

Area = π * (9.5)^2 = π * 90.25 = 90.25π m^2

Therefore, the area of the circle is 90.25π square meters.
