Cal is creating a circular garden for his yard. The radius of the garden is 15 feet. He wants to put fencing around the garden that costs $3 54 perfoot How much will the fencing cost? use 3.14 forpi)A. In order to calculate the diameter is needed. The diameter for Ca's garden is _____ feet B. The circumference (distance around) the garden is _____feet10 vC. The fencing costs $3.54 for each foot of fencing, therefore the fence will cost $_____

Sagot :

A.

The diameter of the garden is given by double the radius.

If the radius is 15 feet, then the diameter is 30 feet.

B.

The circumference is given by the formula:

[tex]C=\pi d[/tex]

Where d is the diameter. So we have:

[tex]\begin{gathered} C=3.14\cdot30 \\ C=94.2 \end{gathered}[/tex]

C.

To calculate the fence cost, let's multiply the circumference by the cost of each foot of fencing:

[tex]\begin{gathered} \text{Cost}=94.2\cdot3.54 \\ \text{Cost}=333.47 \end{gathered}[/tex]

So the cost is $333.47.
