Answer:
(x-5)²+(y-2)²=52
Step-by-step explanation:
first find the midpoint (center of the circle)
(9+1)/2, (-4+8)/2
(5, 2) = center
then distance formula to find diameter
√(9-1)²+(-4-8)²=√64+144 = √208 = 2√52
The radius is half the diameter = √52
Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center
Now you can plug everything in.
(x-5)²+(y-2)²=52
THE ANSWER TO YOUR QUESTION IS 257 INCHES IN TOTAL.
BECAUSE, 21 FEET = 252 INCHES + 5 INCHES = 257
a² + 2ab + b² = (a+b) * (a + b) <span>pattern condensed multiplication</span>
x² + 10x + 25
a² + 2ab + b²
(1x)² + 2*1x*5 + (5)² = (a+b)*(a+b)
a=x 2ab= 10x b=5 = (x+5)*(x+5)
Answer : (x+5)*(x+5)
I only know th first one it is nonconsucutive vertacles
