Answer:
104.73cm²
Step-by-step explanation:
AREA OF SEMI CIRCLE
9cm-4cm = 5cm
5cm is the radius of the semi-circle
(πr²)/2 =
25π/2 = 12.5π
AREA OF SQUARE
16cm*9cm = 144cm²
AREA OF THE FIGURE SHOWN
144cm² - 12.5cmπ²
144cm² - 39.27cm² = 104.73cm²
First lets get the total weight that Hailey bought, that is working with fractions:
1 3/7 = 7/7 + 3/7
= 10/7 = 1.43
so we use a rule of three to solve this:
1.43 kg ------> $13
1 kg --------> x
x = (1)(13)/(1.43)
x = 9.09
therefore a 1kg of sliced salami costs $9.09
I believe this is a problem dealing with proportions, so you could cross multiply and divide. so you would do 8/270 then x/72.5 , you cross multiply 72.5x8 which equals 580. then you divide that answer by 100 which equals 5.8 (:
