Question

question 2 of 10 (1 point) | question attempt: 1 of unlimited (a) use the calculator to find the circumference and area of the courtyard. 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 courtyard will be covered with gravel. which measure would be used in finding the amount of gravel needed? circumference area (c) the courtyard will be paved. which measure would be used in finding the amount of pavement needed? circumference area

Explanation:

Step1: Calculate circumference

Circumference formula: $C = 2\pi r$, $r=24m$, $\pi=3.14$.
$C = 2 \times 3.14 \times 24 = 150.72$ m.

Step2: Calculate area

Area formula: $A = \pi r^2$.
$A = 3.14 \times 24^2 = 3.14 \times 576 = 1808.64$ $m^2$.

Step3: Choose measure for gravel

Gravel covers the surface, so use area.

Step4: Choose measure for pavement

Pavement is the boundary, so use circumference.

Answer:

(a) Circumference: 150.72 m; Area: 1808.64 $m^2$
(b) Area
(c) Circumference
