Answer
88.5 ft²
Explanation
The first step is the surface area of the semicircle.
Surface area of a circle = πr²
= π × 13²
= 530.929 ft²
Since the semicircle, we divide this by 2.
S.A of the parachute = 530.929/2
= 265.4645 ft²
To get the fabric is needed for each color we divide this by 3.
Fabric needed for each color = 265.4645/3
= 88.488 ft²
To the nearest tenth, answer = 88.5 ft²
The total amount of fabric needed to make a single parachute will be 88.5 ft². Each parachute red, white, and blue is of the same area.
It is a polygon that is having an infinite number of sides. It subtends 180 degrees. It has only one variable which is radius or diameter.
Given
Radius of semi-circle = 13 feet
The fourth of July celebration wants each parachute to be made from equal parts of red, white, and blue fabric.
The area of the semi-circle is given by
[tex]\rm Area\ of\ semi-circle &= \dfrac{\pi r^{2} }{2} \\\\Area\ of\ semi-circle &= \dfrac{\pi *13^{2} }{2} \\\\Area\ of\ semi-circle &= 265.46[/tex]
We have three parachutes that are red, white, and blue.
[tex]\rm Area\ of\ each\ parachute\ = \dfrac{265.46}{3} \\\\Area\ of\ each\ parachute = 88.488[/tex]
Hence the approximate value of 88.488 will be 88.5.
Thus. the Area of each parachute is 88.5 square feet.
