The equation of a circle is represented as :
where,
- "h" represents x - coordinate of the center of circle
- "k" represents y - coordinate of the center of circle
- " r " represents Radius of the given circle
So, from above equation we get:
Therefore, Radius of the given circle measures 6 units.
Given:
8.90ft³ for 30 balloons
Let h be the volume of helium and b be the number of balloons.
Using proportion;
b/h = 30 /8.90
Multiply both-side by h
Hence, the answer to blank 1 is the above.
when b=50, substitute for b in the above and solve for the volume (h).
That is;
Multiply both-side by 8.90/30
Hence, the answer to blank 2 is 14.83ft³.
