A round swimming pool has a circumference of 66 feet Carlos snags to buy a rope or put across the diameter of the pool the rope costs $0.45 per foot , and Carlos need 4 feet more than the diameter of the pool. how much will Carlos pay for the rope ?!

The circumference of a circle is the diameter times pi. So, 66 ft = pi x d. 66 divided by pi is roughly 21, so the diameter is 21 ft. 21 + 4 = 25. 25 x $0.45 = $11.25

The amount of money Carlos would pay for the rope is $11.268.

Given the following data:

Circumference of a circle = 66 feet.

Cost of rope = $0.45 per foot.

Required length = 4 feet.

How to calculate the diameter of a circle.

Mathematically, the circumference of a circle is given by the formula:

$Circumference = \pi D$

Where:

D is the diameter of a circle.

Substituting the given parameters into the formula, we have;

$66=3.142 D\\\\D=\frac{66}{3.142}$

D = 21.01 feet.

For the total diameter:

T = $21.01 + 4$ = 25.04 feet.

Now, we can determine the amount of money Carlos would pay for the rope:

$Amount = 25.04 \times 0.45$

Amount = $11.268.
