Answer: Choice B) multiply the radius by 2, then by 3.14
The formula is
C = 2*pi*r
which you can rearrange to get C = 2*r*pi, showing you multiply 2 and the radius r, then multiply by pi = 3.14 which is approximate
A similar related formula is
C = pi*d
where d is the diameter. Note that d = 2*r, so we can replace d with 2r to get the first formula back again.
the circumference is the distance or perimeter around the circle
X=-2 I know because me smart lol
Answer:
5
Step-by-step explanation:
3x5x7x9=945

Answer:
Step-by-step explanation:
We have the equation:
we know that:
14*14 = 196
then:
14 = √196
Now, we can rewrite:
50 = 2*25
98 = 2*49
This is because we know that 49 and 25 are perfect squares, then:
Now we can use the common factor √2 and get:
and we know that:
7*7 = 49
5*5 = 25
then:
the value of b is:
b = 12
