Answer:
.
Step-by-step explanation:
So you have a quarter circle
this area is equal so 1/4 of total area
find total area and diviby by 4
area=pi r^2
diameter=2r
diameter/2=r
diameter=5
5/2=r=2 and 1/2=2.5
equation is now
3.14 times 2.5^2
3.14 times 6.25
19.625
that is total area
now divide by 4
19.625/4=4.9 ft
round to nearest foot
5
answer is 5 ft^2

Step-by-step explanation:
General equation of circle is
---------------------(1)
This circle passes through the given three points, (1,7) , (8,6) and (7,-1).
Substitute (1,7) in (1),
1 +
=0
2g + 14f + c = -50 -------------(2)
Substitute (8,6) in (1),

16g + 12f + c = -100 -----------(3)
Substitute (7,-1) in (1),

14g - 2f + c = -50 ---------------(4)
Solving (2),(3) amd (4) simultaneously,
g = -4
f = -3
c = 0
Equation of circle is
Answer: Trey is correct
Step-by-step explanation: Because 3 x 4 = 12 and 4 x 3 also = 12 so Trey is correct.
