Question

Approximately how much fabric of each color will be needed to make a single parachute canopy? 88. 5 ft 88. 5 ft² 265. 5 ft 265. 5 ft².

Answer 1

The 88.5 ft² fabric of each color will be needed to make a single parachute canopy.

Given

The canopy of a parachute is a semicircle with a radius of 13 feet.

A company that is making parachutes for a Fourth of July celebration wants each parachute to be made from equal parts of red, white, and blue fabric.

What is the surface area of a semicircle?

The area of a semicircle is half of the area of the circle.

The first step is the surface area of the semicircle.

The surface area of a circle is;

$\rm Surface \ area=\pi r^2\\\\Surface \ area=3.14 \times 13^2\\\\Surface \ area =530.929$

Since the semicircle, we divide this by 2.

S.A of the parachute is;

$\rm =\dfrac{530.929}{2}\\\\= 265.4645$

To get the fabric is needed for each color we divide this by 3.

The fabric needed for each color is;

$\rm= \dfrac{265.4645}{3}\\\\=88.5$

Hence, the 88.5 ft² fabric of each color will be needed to make a single parachute canopy.
