2 \pi r=circumference of the circle
r=5.5
(5.5) x^{2}  \pi =area
30.25 \pi =area

30.25\pi square inches is the area for the circle

C= pi d
therefore 11= diameter
radius is 1/2 the diameter
radius= 5.5

A= pi r^2
A=30.25 pi
hope this helps

Sketch the region that is common to the graphs of x ≥ 2,
Oliga [24]

a. Find the graph of their common region in the attachment

b. The area of the common region of the graphs is 8 units²

<h3>a. How to sketch the region common to the graphs?</h3>

Since we have x ≥ 2, y ≥ 0, and x + y ≤ 6, we plot each graph separately and find their region of intersection.

  • The graph of x ≥ 2 is the region right of the line x = 2.
  • The graph of y ≥ 0 is the region above the line y = 0 or x-axis.
  • To plot the graph of x + y ≤ 6, we first plot the graph of x + y = 6 ⇒ y = -x + 6. Then the graph of x + y ≤ 6 is the graph of y ≤ - x + 6.

So, the graph of x + y ≤ 6 is the region below the line y = - x + 6

From the graph, the regions intersect at (2, 0), (2, 4) and (6, 0)

Find the graph of their common region in the attachment

<h3>b. The area of the common region</h3>

From the graph, we see that the common region is a right angled triangle with

  • height = 4 units and
  • base = 4 units

So, its area = 1/2 × height × base

= 1/2 × 4 units × 4 units

= 1/2 × 16 units²

= 8 units²

So, the area of the common region of the graphs is 8 units²

During a huge snowstorm in the white mountains last year, it snowed 62.5 cm in one day. how much did it snow in meters?
makkiz [27]
Cm is a centimeter, which is one-hundredth of a meter. Or rather, one hundred centimeters is equal to one meter.

To convert cm to meters

(62.5 cm) * (1 meter/100 cm) = .625 meters
