2 answers:
Answer:
The radius of the circle with circumference 22cm is 3.5 cm
Step-by-step explanation:
The circumference of circumference of a circle is the distance of its closed boundary.
The circumference of a circle with radius r is given by the formula:
Given
C = 22cm
Putting the values in the formula
Hence,
The radius of the circle with circumference 22cm is 3.5 cm

Answer:
Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, <em>or</em><em> </em>insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
<em><u>Point-slope form:</u></em>
Where:
is the slope
and
are corresponding coordinate points
Insert the given values:
Solve for y. Expand the right sie using the distributive property:
Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:
<em>OR</em>
<em></em>
<em><u>Slope-intercept form:</u></em>
Where:
is the y-intercept
and
are corresponding coordinate points
Insert the given values:
Simplify the multiplication:
Solve for b. Add 10 to both sides, canceling out the 10 on the right:
The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:
