Semmy [17]

Answer:

$95.38

Step-by-step explanation:

step 1

Find the area of one button

The area is equal to

A=\pi r^{2}

we have

r=9/2=4.5\ cm ---> the radius is half the diameter

Convert to meters

r=4.5\ cm=4.5/100=0.045\ m

assume

\pi =3.14

substitute

A=(3.14)(0.045)^{2}\\A=0.0063585\ m^2

step 2

Find the area of 1,00 buttons

Multiply by 1,000

A=0.0063585(1,000)=6.3585\ m^2

step 3

Find the cost

Multiply $15 per square meter by the total area of 1,000 buttons

(15)6.3585=\$95.38
