This is simple:
If k=3/5, then you substitute 3/5 for k
Example:
5(3/5)(-7)=?
Answer: -175/3 or -58.33 repeating
Step-by-step explanation:
you did not even try a calculator to find the result ?
64 is 8×8 or 8².
so, sqrt(64) = 8.
similarly for 4 :
4 is 2×2 or 2².
so, sqrt(4) = 2
so,
sqrt(64)/ sqrt(4) = 8 / 2 = 4
so, d. is the right answer.

Answer:
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to

we have

substitute


step 2
Find the approximate length of arc s
we know that
The circumference of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the length of arc for a central angle of 330 degrees

----> exact value
assume

----> approximate value
