Answer: No, 40 months isn’t reasonable.

Step-by-step explanation:

For Shellie: 40*3 = 120 cm in 40 months

For Carley: 40*2 = 80cm in 40 months

Next we add the amount of hair they have already to the amount of centimeters would grow.

Shellie: 120+10 = 130cm

Carley: 80+20 = 100cm

So if the girls wanted to cut their hair at the exact length, 40 months isn’t a reasonable solution.

The circle below has center P, and its radius is 3 m. Given that m 2 QPR=170°, find the length of the minor arc OR.

QveST [7]

Any smooth curve connecting two points is called an arc. The length of the arc m∠QPR is 2.8334π m.

<h3>What is the Length of an Arc?</h3>

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

$\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}$

where

θ is the angle, that which arc creates at the centre of the circle in degree.

Given the radius of the circle is 3m, while the angle made by the arc at the centre of the circle is 170°. Therefore,

The length of an arc = 2πr×(θ/360°) = 2π × 3 ×(170/360°) = 2.8334π m

Hence, the length of the arc m∠QPR is 2.8334π m.
