If you are using a calculator, simply enter 78÷260×100 which will give you 30 as the answer.
Answer:
615.44 m²
Step-by-step explanation:
the area of circle = 3.14 x 14² = 3.14×196
= 615.44 m²
Answer:
The minimum y-value is
or 
Step-by-step explanation:
we have

This is the equation of a vertical parabola open up
The vertex is the minimum y-value on the graph
Convert the equation into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares

------> equation in vertex form
The vertex is the point (-0.5,-7.75)
therefore
The minimum is the point (-0.5,-7.75)
The minimum y-value is 
see the attached figure to better understand the problem
Answer C or 1,050 is the correct answer
I’m not quite sure if you are saying each side is 7 or 77 so I did both.
If the side length is 7, then 9.9 is the answer.
If the side length is 77, then 108.9 is the answer.
