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

$(15)6.3585=\$95.38$

In the triangle below, the value of a is 12.6.<br><br> True<br><br> False

aev [14]

Answer:

True

Step-by-step explanation:

Formula

Tan(x) = opposite / adjacent

Givens

x = 42

adjacent = 14

opposite = ?

Solution

Tan(42) = opp/14 Find tan(42)

Tan(42) = 0.900404

0.900404 = opp/ 14 Multiply both sides by 14

14 * 0.900404 = opp/14 * 14 Simplify the left

12.6 rounded = opp

a = 12.6
