Answer:
r = 4 inches
Step-by-step explanation:
The radius of a circle is 1/2 of the diameter
r = 1/2d
r = 8/2 = 4
The area of each pizza and cost per inch is $12.82 per square inches and $11.304 per square inches respectively.
<h3>How to solve area of a circle?</h3>
Large:
Diameter = 14 inches
Radius, r = 14 / 2
= 7 inches
Area = πr²
= 3.14 × 7²
= 3.14 × 49
= 153.86 square inches
Cost per inch = 153.86 square inches / 12
= 12.8216666666666
Approximately, $12.82 per square inches
Medium:
Diameter = 12 inches
Radius, r = 12/2
= 6 inches
Area = πr²
= 3.14 × 6²
= 3.14 × 36
= 113.04 square inches
Cost per inch = 113.04 square inches / 10
= $11.304 per square inches

A.) If Lucy sells 1 necklace, her sales would equal to $15.99. Then her profit would be:
Profit = $15.99 - $3.38(1) - $5.57(1)
Profit = $7.04
The fraction of the sale price of the necklace in profit is denoted as x.
15.99x = 7.04
x = 704/1559
b.) This is the same as part (a) but in decimal form. Just simply divide 704 by 1559. The answer is 0.44
c.) If Lucy's sales is $223.86 and each necklace costs $15.99, then the number of necklaces sold is $223.86 ÷ $15.99/necklace = 14 necklaces
Her profit for the 14 necklaces sold would be:
$223.86 - $3.38(14) - $5.57(14) = $98.56
Answer:
the sides will not be equal, they will be proportionate
Step-by-step explanation:
