Permutation so 5!/(5-3)!=5!/2!= 5 x 3 x 4= 60 ways.
When you divide numbers, you make the value smaller. So subtract the exponents will make the value with that base smaller.
We are unable to answer this question without being able to see the graph.
The formula for circumference is
or
. We have a diameter for the semicircle, so let's use the diameter formula.
which is either
or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069
