Answer: 68400
Explanation: The question is asking for area so you do base times height. In this case you multiply 360 times 190.
Answer:
Equation = (x - 6 )² + ( y + 3 )² = 9
Step-by-step explanation:
The circle passes through ( 6, 0) and ( 6 , -6)
They are the coordinates of the diameter.
Using this we can find the centre of the circle.
<u>Find the centre of the circle.</u>
Centre of the circle is the mid- point of (6, 0) and ( 6, -6)


<u>Find the radius of the circle.</u>

Diameter is the distance between the points (6 , 0) and ( 6, - 6)


Therefore,

<u>Standard equation of a circle:</u>

Therefore , equation of the circle ;

The first two are already in slope intercept form. The third is y=2/5x-2. The fourth is y=4x+8.
