Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .

The arc length is a quarter of the circumference of the full circle, so 2πr/4.

The straight sides are both radii, so each length r.

Total perimeter

p = 2πr/4 + r + r = r(π/2 + 2)

We put in r=2, π=3.14 and get

p = (2(3.14/2 + 2)) = 3.14 + 4 = 7.14

7.14 km

The perimeter is also known as the circumference. The formula for the circumference is C = pi x diameter.

Step 1) Find the diameter

d = r x 2

d = 2 x 2 = 4 km

Step 2) Find the whole circumference

C = pi x 4

C = 4pi km

Step 3) Find 1/4 of the circumference

4pi x 1/4 = 1pi

1pi = 3.14

Step 4) Add the sides not part of the arc

3.14 + 2 + 2 = 7.14

C = 7.14 km

Hope this helps! :)

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

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 =.

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

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

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

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

slope of the solid line would be =.

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
