Work Step by Step
The metal strips are sold in length of 6 ft
We need to find the number of pieces of strip required
The total length of the metal strip = The circumference of the circle = 56.54 ft
Number of metal strips = $\frac{56.54}{6}$ = 9.42 $\approx$ 10
Around 10 metal strips should be needed.
