Question

(a) use the calculator to find the area and circumference of the lawn. use 3.14 for π in your calculations, and do not round your answers. make sure to include the correct units. area:
circumference:
(b) the lawn will be surrounded by tape. which measure would be used in finding the amount of tape needed?
○ circumference
○ area
(c) fertilizer will be applied to the lawn. which measure would be used in finding the amount of fertilizer needed?
○ circumference
○ area

Explanation:

Step1: Identify the radius

The given length is the radius: $r = 46$ ft.

Step2: Calculate circumference

Formula: $C = 2\pi r$. Substitute $\pi = 3.14$, $r = 46$:
$C = 2 \times 3.14 \times 46 = 288.88$ ft.

Step3: Calculate area

Formula: $A = \pi r^2$. Substitute values:
$A = 3.14 \times 46^2 = 3.14 \times 2116 = 6644.24$ ft².

Step4: Answer (b)

Tape around the lawn needs circumference.

Answer:

Circumference.

Step5: Answer (c)

Fertilizer amount depends on area.
