-45.6 is the answer if you evaluate
We know that
<span>Vertex (0, 0) and directrix y = 4
is a vertical parabola------> open down (directrix above the vertex)
the equation is of the form
(y-k)=4p(x-h)</span>²--------> y=4p*x²-------> vertex (0,0)
y=4
y=h-p-----> y=-p
p=-4
the equation of the parabola is
y=-16x²
the answer isy=-16x²
see the attached figure
The answer is 71.6 ft^2.
It is given that 2πR=30 therefore R=4.77(aprox.)
Now you take the area formula:πR^2 which is equal to 71.6
The container will be 270 square centimeters.
