ANSWER
(2). 88.5 ft²
EXPLANATION
The parachute is in the form of a semicircle, so the area of the entire parachute can be calculated using the formula,
Area=½ πr²
The radius is 13cm.
We substitute the radius to get
[tex]Area= \frac{1}{2} \pi \times {13}^{2} [/tex]
[tex] = 265.46457922834 \: \: {ft}^{2} [/tex]
The company required that, each parachute be made from equal parts of red, white, and blue fabric.
Hence, the fabric of each color needed is
[tex] = \frac{265.46457922834}{3} = 88.4882[/tex]
To the nearest tenth, we have,
[tex] = 88.5 {ft}^{2} [/tex]
