Answer:
(0, -1)
Step-by-step explanation:
that is where the line intercepts on the vertical axis
So here, ABCD is being inscribed in a circle, so ABCD is a cyclic quadrilateral (as inscribed in a circle) also, there exists a property of cyclic quadrilateral, i.e, the sum of opposite angles of a cyclic quadrilateral is 180°, so we can just write the following equation using this :




Answer:
1. 7 , 2. 4, 3. 29, 4. 71
Step-by-step explanation:
Answer:
113.04 units^2
Step-by-step explanation:
The area of a circle can be found using:

First, we need to find the radius, since we have the diameter.
<u />
<u><em>Radius</em></u>
The radius is half the diameter, or
r=d/2
We know the diameter is 12, so we can substitute that in
r=12/2 <em>Divide </em>
r=6
<u><em>Area </em></u>
Now we know the radius and can substitute it into the area formula

<em>Solve the exponent </em>

Substitute 3.14 in for pi
a=3.14*36 <em>Multiply </em>
a=113.04
We aren't given a specific unit, so we can say the area is
113.04 units^2
