answer

$25\pi {ft}^{2}$

explanation

the area of a circle is calculated using the formula

$area =\pi {r}^{2}$

$area = \frac{\pi \: {d}^{2} }{4}$

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

$d = 10ft$

we substitute the diameter into the formula to get:

$area = \frac{\pi \: \times {10}^{2} }{4}$

$area = \frac{100\pi}{4}$

$area = 25\pi {ft}^{2}$

this is the exact value for the area of the circle.

the correct answer is a

1. 25pi ft^2 2. 5pi ft^2 3. 10pi ft^2 3. 20pi ft^2

$y> \frac{1}{3}x$ and y≤ -x +4 .

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be = $\frac{1-0}{3-0} = \frac{1}{3}$ .

y-intercept of dotted line is y=0 only.

plugging slope m= $\frac{1}{3}$ and b=0 in slope-intercept form y=mx+b, we get

$y=\frac{1}{3}x$ .

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

$y> \frac{1}{3}x$ .

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be = $\frac{4-1}{0-3} = \frac{3}{-3}=-1$ .

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

y≤ -x +4 .
Write a system of inequalities to represent the shaded portion of the graph.
