The equation of the circle x² +y² – 8x – 6y + 21 = 0 is equal to the equation (x + 4)² + (y − 3)² = 2². Then the correct option is C.
<h3>What is a circle?</h3>
It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
x² + y² – 8x – 6y + 21 = 0
The equation can be written as
x² – 8x + 16 + y² – 6y + 9 = 4
(x + 4)² + (y − 3)² = 2²
Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.

Distribute the 3/4 into the parenthesis.
should get (15/4)Z+ 48/4
then simplify
Final answer= (15/4)Z+12
Answer:
neither, would technically be intersecting lines tho
Step-by-step explanation:
Irrational because it’s not a perfect square.

A. Area of given figure = 280 + 77 = 357 cm²
B. length of semicircle = 22 cm
