Answer:
Approx. 1.8 in.²
Step-by-step explanation:
Circumference of a circle (the pizza) = 2πr
Area of a circle = πr²
Set 2πr = 4.71 (because that's the length of bacon around the pizza) and solve for the radius "r". Then plug that "r" into the area equation πr² to find the area. You should get 1.8 square inches if I plugged them in correctly.
Hello!
You have to find 45% of 2,920
First change 45% to a decimal
To change percents to decimal, remove the % sign and add a decimal point 2 places to the left.
45% = 0.45
<em>Now multiply</em>
0.45 × 2,920 = 1,314
There are <u>1,314 </u>advertising pieces
6/9=x/21
x=21*6/9
=126/9
x=14
