Answer:
12.5
Step-by-step explanation:
In order to solve, we need to add 9 to both sides of the equation:
<u>Our sum applied:</u>
b=12.5
Step-by-step explanation:
Given diameter of table (circular) =1.6m
radius =0.8m
area of circle = πr
2
=3.14×0.64=2.0096m
2
Now rate of polishing per meter square =15Rs
Cost of polishing table top = 15×2.0096
cost = 30.14m

The equation of a
circle is:
(x - h)² + (y - k)² = r²
The equation of a
parabola is:
(x - h)² = 4p(y - k)
The equation of an
ellipse is:

where variables a and b and the two different measurements of the vertices
The equation of a
hyperbola is:

if it is with a horizontal transverse axis

if it is with a vertical transverse axis
Notice these have a subtraction operation, the exact opposite ellipse.
