Answer:
It would probably be 15 actually
Answer:
15/32
Step-by-step explanation:
Answer:
a = 0
Step-by-step explanation:
a + 5 = -5a + 5 subtract 5 from both sides
a + 5 - 5 = -5a + 5 - 5
a = -5a add 5a to both sides
a + 5a = -5a + 5a
6a = 0 divide both sides by 6
6a / 6 = 0 / 6
therefore,
a = 0
Answer:
Step-by-step explanation:
strategy: find the distance of the two points, take half of that, b/c that will be the radius, Then use the area of a circle formula to find the answer
P1 = (1,-1) in the form (x1,y1)
P2= ((3,3) in the form (x2,y2)
dist = sqrt [ (x2-x1)^2 + (y2-y1)^2 ]
dist = sqrt [ 3 -1 )^2 + 3-(-1)^2 ]
dist = sqrt [ 2^2 + 4^2 ]
dist = sqrt [ 4 + 16 ]
dist = sqrt [20]
r =
/2
area of circle = 

area of circle =
(
/2)^2
area of circle =
(
/2)(
/2)
area of circle =
(20 / 4)
area of circle =
5
area of circle = 5
