A landscaper is designing a circular flower bed with a diameter of $10$ feet. She needs to install a flexible plastic border completely around the outer edge of the flower bed. What is the total length, in feet, of the plastic border needed? Use $\pi = 3.14$ .

Cevap: 31.4 feet

Cevap

31.4

The problem asks for the length of a border around a circle, which is the circumference. The circumference is found by multiplying the diameter (

10

feet) by

\pi

(

3.14

), resulting in

31.4

feet.

Adım Adım Çözüm

Determine the required measurement

Calculate the circumference

The plastic border goes around the outer edge of the flower bed.

Select the correct formula

C = \pi \times d

We are given the diameter (

10

feet) and need the circumference.

Calculate the circumference

3.14 \times 10 = 31.4

Substitute

\pi = 3.14

and

d = 10

into the formula.
