Given:
The equation of the parabola is:
To find:
The y-intercept of the parabola.
Solution:
We have,
Putting in the given equation, we get
Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).
Answer:
Area of circle = 50.24 units
Option J is correct answer.
Step-by-step explanation:
We need to find the area of a circle with centre (2, 3) that passes through (2,7)
The formula used to find area of circle is:
We need to find radius.
The radius can be found using the distance between points (2,3) and (2,7)
The The distance formula is:
Putting values and finding length
We have:
Putting values and finding distance
So, we found Distance = 4
Therefore, the radius of circle is 4
Now, finding area:
So, Area of circle = 50.24 units
Option J is correct answer.
