The total length of wire needed to fasten 175 bundles is 2,975 cm.

UkoKoshka [18]

According to the conversion table we know,

1 meter = 100cm

This means if we need to convert meters to centimeters, we need to multiply by 100

Or

If we need to convert from centimeters to meters, we need to divide by 100.

Here the length of the wire needed to wrap 175 bundles = 2975 cm.

Now as we need to convert it to meters.

We need to divide this by 100.

We get

2975/100= 29.75

So 2975 cm = 29.75 m

Option D) is the right answer

*Mastery Check. DO NOT ask for help. Find the area of the sector. Round your answer to the nearest tenth.

Juliette [100K]

The area of the sector is 472.6 ft²

<h3>Area of a Sector</h3>

For finding the area of the sector, you need apply the formula:

$A=\pi r^2* \frac{\alpha }{360}$ , where:

r= radius

α= central angle

The question gives:

r= radius= 19 ft

α= central angle = 150°

Thus, the area of the sector will be:

$A=\pi r^2* \frac{\alpha }{360}=\pi *19^2*\frac{150}{360} =472.6$
