To answer this question you need to know the conversion rate from kilometer into cm. For every kilometer it would be 1000m and for 1m it will be 100cm. That mean 1km is equal to 100,000cm or 10^5 cm. Then the answer would be:
(3.34 * 10^5 cm) * (1km/10^5cm)= 3.34km

Check the picture below.
now, let's notice the larger "yellow" semicircle, it has a gap, the gap on the right is of a semicircle with a diameter of 10, BUT it also has a descender on the left, a part that's hanging out, that part is also a semicircle.
so if we use the descending semicircle to fill up the gap on the right, we'll end up with a filled up larger semicircle, whose diameter is 20, and whose radius is 10 cm.

Answer:
f(x) = 2(x+3)^4
Step-by-step explanation:
vertical stretch is always outside parenthesis and left and right shift is always inside parenthesis with left being adding the number while right being subtracting the number.
