Answer:
11700 mm²
Step-by-step explanation:
A rectangle is a quadrilateral with two equal, opposite and parallel sides. Each of the angles in a rectangle is 90°.
The horizontal distance of the rectangle = r + r + r + r = 4r
The vertical distance = r + h + r = 2r + h
Where h is the distance between the midpoint of the 2 up circles and the midpoint of the down circle.
Using Pythagoras:
(2r)² = h² + r²
h² + r² = 4r²
h² = 3r²
h = √3r²
h = r√3
Vertical distance = 2r + h = 2r + r√3
Area of rectangle = vertical distance * horizontal distance
Area = 4r * (2r + r√3) = 8r² + 4r²√3 = 4r²(2 + √3)
Substituting:
Area = 4r²(2 + √3) = 4(28²)(2 + √3) = 11703.711 mm²
Area = 11700 mm² to 3 s.f

Answer:
22.99 inches
Step-by-step explanation:
According to problem, given data are as follows:
Fabric used for headband = 595.56 inches
Number of headbands made = 39 + 3 = 42
So, Fabric used per headband = 595.56 ÷ 42 = 14.18 inches per headband
Similarly, Fabric used for wristband = 343.59 inches
Number of wristbands made = 39
So, Fabric used per wristband = 343.59 ÷ 39 = 8.81 inches per wristband
So, Fabric used for each player = 14.18 inches + 8.81 inches
= 22.99 inches
