The circumference of a circle is always calculated by 2
R
So if R=2.5 m this circumference is 2*
*2.5 m
Which is 5
m (choice B)
Hope this helped!
Answer:
c
Step-by-step explanation:
Answer:
First, we need to determine the slope of the line going through the two points. The slope can be found by using the formula:
m
=
y
2
−
y
1
x
2
−
x
1
Where
m
is the slope and (
x
1
,
y
1
) and (
x
2
,
y
2
) are the two points on the line.
Substituting the values from the points in the problem gives:
m
=

Now, we can use the point-slope formula to find an equation going through the two points. The point-slope formula states:
(
y
−
y

)
=
m
(
x
−
x
1
)
Where
m
is the slope and
(
x

y

)
is a point the line passes through.
Substituting the slope we calculated and the values from the first point gives:
(
y

)
=

(
x

)
We can also substitute the slope we calculated and the values from the second point giving:
(
y
−
5
)
=
−

(

)
We can also solve the first equation for
y
to transform the equation to slope-intercept form. The slope-intercept form of a linear equation is:
y
=
m
x
+
b
Where
m
is the slope and
b
is the y-intercept value.
