$22x5% = $1.10 or 22x.05= 1.1
$22.00 + $1.10 = $23.10
Answer:
The arc length of the semicircle is
or 
Step-by-step explanation:
The complete question in the attached figure
we know that
The circumference of a semicircle is given by the formula

where
D is the diameter of the semicircle
we have

substitute

----> exact value
Assume

----> approximate value
therefore
The arc length of the semicircle is
or 
Answer:
227.5 grams
Step-by-step explanation:
We know that a single 10p coin weights 6.5 g
Now we want to find the weight of a bag of 10p coins, such that the net value is £3.50 (where the weight of the bag is neglected)
The value of a 10p coin is £0.10
So the first thing we need to find, is how many coins there are in the bag.
To find that, we need to find the quotient between the total value and the value of a single coin:
£3.50/£0.10 = 35
So in the bag, we have 35 coins, and each one of them weighs 6.5 grams
Then the total weight is 35 times 6.5 grams:
35*6.5 g= 227.5 grams
As far as I can tell, is referring and assuming the ruler doesn't have any fractional values, namely it only has markings with integers.
so in short is asking, what are the two integers that the fractional 5¼ is between?
