The area of a circle is <u>(pi) x (the circle's radius)</u>²
The circle's radius is (1/2) of (its diameter).
Area = (pi) x (12/2 inches)² =
(pi) x (6 inches)² =
(3.14) x (36 square inches) = <em>113 square inches</em> (rounded)
Answer:
Selling price should be $21 per unit.
Step-by-step explanation:
Cost price of manual = Fixed price + variable cost per package×Number of units sold
= 780000+19.85×1250000 = $25592500
Now we know Learning center wants a profit = $650000
Then profit = sale price - cost price
650000=sale price - 25592500
Sale price = 650000+25592500 = $26242500
This is the sale price of 1250000 units then selling price per unit should be = Total selling price/Number of units sold
= $26242500/1250000 =20.994 or $21
Selling price should be $21 per unit.
