Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm
Answer:
0
Step-by-step explanation:
slope= (y2-y1)/(x2-x1)
= [-2-(-2)]/[9-3]
=[-2+2]/6
=0/6
=0

Answer:
N=i
S = -i
E =1
W = -1
Step-by-step explanation:
If facing north is represented by i, then facing south would be the opposite or -i.
We can let facing east be 1 because the magnitude has to be 1, so facing west would be the opposite or -1
48.33%
Explanation:
Simple way to find percentages of two numbers, is to make it into a fraction.
58/120 then divide 58 by 120.
You can also multiply 58•100 then divide by 120 to get it in a percentage without having to convert.
Which is .4833(33)
Or 48.33%

3x + 2 = 2x + 7
Subtract 2 from both sides:
3x = 2x +5
Subtract 2x from both sides:
x = 5
Answer: x = 5
