You have the formula already, just plug in 30 for s (speed) and solve for d (distance).
Answer:
13.9mm
Step-by-step explanation:
short story, pythagorean theorem a²+b²=c²
a=13.5
b=3.2
c=?
13.5² = 182.25
3.2² = 10.24
c² = 192.49
c = 13.8740765458
round to 1 decimal place c = 13.9
Answer:
x=18
Step-by-step explanation:
7x+15=141
7x=141-15
7x=126
7/7=126/7
x=18
have a good day!

Circumference of the smaller circle, using
, is approximately equal to 18.85 (I used the high floating point precision approximation of pi my calculator has in memory, then rounded to 2 decimal points.)
Using the formula
, which in English says "the smaller circle's circumference is equal to 20% of the larger circle's", we can substitute the known value S:
and solve for L:
.
So the larger circle has a circumference approximately equal to 92.5 units.
