Question

(a) use the calculator to find the circumference and area of the lawn. use 3.14 for π in your calculations, and do not round your answers. make sure to include the correct units. circumference: area: (b) the lawn will be colored with dye. which measure would be used in finding the amount of dye 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 circle's radius is 44 ft.

Step2: Calculate circumference

Circumference formula: $C = 2\pi r$. Substitute $\pi=3.14$, $r=44$:
$C = 2 \times 3.14 \times 44 = 276.32$ ft.

Step3: Calculate area

Area formula: $A = \pi r^2$. Substitute values:
$A = 3.14 \times 44^2 = 3.14 \times 1936 = 6079.04$ ft².

Step4: Answer (b)

Dye covers surface area, so use Area.

Step5: Answer (c)

Fertilizer uses surface area, so use Area.

Answer:

(a) Circumference: 276.32 ft; Area: 6079.04 ft²
(b) Area
(c) Area
