Find the distance around a circular fountain if the radius of the fountain is 7ft long.

I did this:
C=pi*D
22/7*3.5/1
11ft long

DOn't know why you halved the radius when you should have doubled it to obtain the diameter.

S = 3.14(7)2 - 43.98 ft.

O yes your right. Thank you.

To find the distance around a circular fountain, you need to calculate the circumference of the circle. The formula for the circumference of a circle is C = π * D, where C represents the circumference and D represents the diameter.

In this case, you are given the radius of the fountain, which is 7ft. To find the diameter, you need to double the radius, so the diameter is 7ft * 2 = 14ft.

Now, substitute the value of the diameter into the formula: C = π * D = π * 14ft.

Using the approximation of π as 22/7, we can calculate the circumference: C ≈ (22/7) * 14ft.

Simplifying the calculation gives C ≈ 22ft.

Therefore, the distance around the circular fountain is approximately 22ft.
