Answer:
4
Step-by-step explanation:
The perimeter of the region is equal to the sum of the perimeter of the four semicircular arc. Since the semicircular arcs have the same measure, therefore:
Perimeter of region = 4 × Perimeter of semicircular arc.
The side of the square = diameter of the semicircle = 2/π.
The radius of semicircle = diameter/2 = 
The perimeter of a semicircle = perimeter of a circle ÷ 2
The formula for a circle is pie times radius square so it’s gonna be 3.14 x 8 x 8
So 8 x 8 = 64
Then you will mutiply that by 3.14
So you will be 200.96
200.96
200 meters per minute.
A minute is 60 seconds. 60 divided by 3 is 20. 20 Times 10 is 200.
Answer:
x-int (6.2, 0)
y-int (0, 3.1)
Step-by-step explanation:
x-intercept is found when y = 0.
y-intercept is found when x = 0.
Step 1: Define equation
2x + 4y = 12.4
Step 2: Find x-intercept
<em>Substitute y for 0.</em>
2x + 4(0) = 12.4
2x = 12.4
x = 6.2
(6.2, 0)
Step 3: Find y-intercept
<em>Substitute x for 0.</em>
2(0) + 4y = 12.4
4y = 12.4
y = 3.1
(0, 3.1)
