Sagot :
Answer:
$8 per foot
Explanation:
Diameter of the circular flowerbed = 7 feet
Radius of the circular flowerbed = 7/2 = 3.5 feet.
Since she wants to plant roses around the edge, we deal with the circumference.
Circumference of a circle = 2πr
Therefore:
[tex]\begin{gathered} \text{Cirumference of the flowerbed=2x }\pi\times3.5 \\ =21.99\text{ ft} \end{gathered}[/tex]If the total cost of planting roses is $176
The unit price of planting roses per foot
[tex]\begin{gathered} =\frac{\$176}{21.99ft} \\ =\$8\text{ per foot} \end{gathered}[/tex]The unit price of planting roses is $8 per foot.
