Question

(a) use the calculator to find the area and circumference of the park. use 3.14 for \\(\pi\\) in your calculations, and do not round your answers. make sure to include the correct units.\
area: \\(\square\\)\
circumference: \\(\square\\)\
(b) a rope will be placed around the park.\
which measure would be used in finding the amount of rope needed?\
\\(\bigcirc\\) circumference \\(\bigcirc\\) area\
(c) the park will be covered by artificial turf.\
which measure would be used in finding the amount of turf needed?\
\\(\bigcirc\\) circumference \\(\bigcirc\\) area\
(there is a circle with radius 28 yd in the image)

Explanation:

Step1: Calculate area of the park

Area formula: $A = \pi r^2$. $r=28$ yd, $\pi=3.14$.
$A = 3.14 \times 28^2 = 3.14 \times 784 = 2461.76$ yd².

Step2: Calculate circumference of the park

Circumference formula: $C = 2\pi r$.
$C = 2 \times 3.14 \times 28 = 175.84$ yd.

Step3: Answer sub-question (b)

Rope around the park uses circumference.
Correct option: A. Circumference.

Step4: Answer sub-question (c)

Turf covers the park's area.
Correct option: B. Area.

Answer:

Area: 2461.76 yd²
Circumference: 175.84 yd
(b) A. Circumference
(c) B. Area
