I want to check my answer someone help!!

A piece of rope 94.2 inches long will enclose a circular childs wading pool what is the diameter of the pool?
A. 15in
B. 47.1 in **
C. 30 in
D. 31.4 in

no. the diameter is not 1/2 of the circumference.

Recall that C = πd
Try again.

Hint: pi is NOT 3 !

Is the answer D?

No. Divide C by pi.

To find the diameter of the circular child's wading pool, we can use the formula for the circumference of a circle.

The formula for the circumference of a circle is: C = π * d, where C is the circumference and d is the diameter.

Given that the length of the rope is 94.2 inches and we want to find the diameter, we can rearrange the formula as follows:

C = π * d
94.2 = π * d

Now, we can solve for d by dividing both sides of the equation by π:

94.2 / π = d

Using a calculator, we can approximate the value of π to be 3.14:

94.2 / 3.14 ≈ 30

Therefore, the diameter of the circular child's wading pool is approximately 30 inches.

Looking at the available answer choices, option C, 30 inches, is the closest match to our calculated diameter. So, the correct answer is C. 30 in.
