Answer:
Option B.
Step-by-step explanation:
we know that
If a ordered pair lie on the circle. then the ordered pair must satisfy the equation of the circle
step 1
Find the equation of the circle
we know that
The equation of the circle in center radius form is equal to
where
r is the radius of the circle
(h,k) is the center of the circle
substitute the values
step 2
Verify each case
case A)
substitute the value of in the equation of the circle and then compare the results
------> is not true
therefore
the ordered pair Q not lie on the circle
case B)
substitute the value of in the equation of the circle and then compare the results
------> is true
therefore
the ordered pair R lie on the circle
case C)
substitute the value of in the equation of the circle and then compare the results
------> is not true
therefore
the ordered pair S not lie on the circle
case D)
substitute the value of in the equation of the circle and then compare the results
------> is not true
therefore
the ordered pair T not lie on the circle
Answer:
Step-by-step explanation:
So first, lets solve for the intercepts.
Let’s start by finding the x intercept.
Plug in 0 for y.
10x+9(0)=-90
10x=-90
X=-9, so your first point on your line will be (-9,0).
Now the y intercept.
Plug in 0 for x.
10(0)+9y=-90
9y=-90
Y=-10, so your second point on your line will be (0,-10).
Use those points to create your line.
Answer: 4 2^ + 5

Your formula here is A=pir^2
Plug in the numbers but instead use 22/7 for pi
A=(22/7)(21)^2
A=22/7*441=1386
Answer is 1386 sq inches
22^7 - 22^4 = 2,494,123,632 .
