To start, the equation has to be converted to slope-intercept form, or . Start by subtracting x from both sides;
,
. Switch 4 and -x around to conform to the formula;
. Then divide by 2 to isolate y;
. This is the final equation. Because the slope of a line perpendicular is always the opposite reciprocal (i.e. The opposite reciprocal of 4 is
, the opposite reciprocal of
is 5) the opposite reciprocal of
is 2. So the equation of the line is
, and the answer is A.
ANSWER
• Circumference: 18.84 ft
,• Area: 28.26 ft²
EXPLANATION
The circumference of a circle of radius r is,
In this case, the radius is r = 3 ft and we have to use 3.14 for π,
Hence, the circumference of this circle is 18.84 feet.
The area of a circle of radius r is,
In this case, r = 3 ft and π = 3.14,
Hence, the area of this circle is 28.26 square feet.
