Answer:
B √8
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
The center of the circle is (1, 6).
(x − 1)² + (y − 6)² = r²
The circle passes through the point (-1, 8).
(-1 − 1)² + (8 − 6)² = r²
4 + 4 = r²
r = √8
Answer:
A.
Step-by-step explanation:
Determine the area of all the faces of the and then devide by 0.15
Step-by-step explanation:
given points (2,0) and (-1,1)
let A(2,0) and B(-1,1)
A(2,0) B( -1,1 )
(x1 , y1) (x2 , y2)
AB = √(x2 - x1)² + (y2 - y1)²
= √(-1 - 2)² + ( 1 - 0 )²
= √(-3)²+ 1²
= √9 + 1
= √10
Therefore,distance between given points is √10
