Answer:
311
Step-by-step explanation:
Taking a pizza to be a circle
Area of big pizza be x abd are of small pizza be y
hence difference = x-y
Area of a circle = where r is the radius
taking to be 3.14
hence area x = 3.14 ( *) = 1017.36
Area y = 3.14 ( * )= 706.5
x-y = 1017.36- 706.5 =310.86
310.86
Yup that is correct, that is the way to convert measurements of angle from radians to degrees. because 2pi is equivalent to one revolution of a circle and in degrees is equal to 360 degrees, then simplifying it 360 / 2pi = 180 / pi.
so <span>the measure of 0 is A radians and B degrees, then A = 180 B/pi</span>
Cost per ounce means you take the cost and divide it by the cost:
<span>3.36 / (21/2) </span>
<span>division of fractions changes to the multiplication of the reciprocal: </span>
<span>3.36 * (2 / 21) </span>
<span>3.36 and has 21 as a factor, so let's cancel it: </span>
<span>0.16 * 2 </span>
<span>$0.32 per ounce</span>
1/4 + 1/10 = 5/20 + 2/20 = 7/20 = 0.35
5.25/0.35 = 15
