What is the area of the shaded region?

Round your final answer to the nearest hundredth.

351.86 Square inches (to the nearest hundredth)

Step-by-step explanation:

The shaded region is referred to as the Annulus of two concentric circles.

To find the area of the shaded region is to subtract the area of the smaller circle from the area of the larger circle.

Let the radius of the larger circle=R

Let the radius of the smaller circle=r

Area of shaded region

R=11cm, r=3cm

Therefore:

Area of shaded region

The Answer is 351.86 (Rounded to the nearest Hundredth)

Step-by-step explanation:

First, calculate the area of the whole figure, including the unshaded area which is 11cm.

The Area of a circle is πr^2 or Pi times radius squared.

π * 11cm * 11cm = 121π cm^2

Next, calculate the area of the inner figure which is 3cm

π * 3cm * 3cm = 9π cm^2

Finally, subtract the area of the inner circle from the area of the outer circle.

121π cm^2 - 9π cm^2 = 112π cm^2

≈ 351.86cm  

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.
