Answer:

$531\:\text{students}$

Step-by-step explanation:

This question implies a constant rate or proportion to estimate the number of students who may choose chocolate from a larger sample size. Therefore, we can set up the following proportion and solve:

$\frac{59}{200}=\frac{x}{1800},\\\\x=\frac{1800\cdot 59}{200},\\\\x=\boxed{531}$

2. Find the area and circumference of the circle to the right.<br>16.6 m<br>

adoni [48]

Answer:

AREA:

$A=216.42m^2$

CIRCUMFERENCE:

$C=52.15m$

Step-by-step explanation:

The formula that is used to calculate the area of a circle is:

$A=\pi r^2$

Where "r" is the radius of the circle.

The formula for calculate the circumference of a circle is:

$C=2\pi r$

Where "r" is the radius of the circle.

Then, you need to find the radius. This is:

$r=\frac{16.6m}{2}=8.3m$

Substituting the radius, you get that the area and the circumference are:

AREA:

$A=\pi (8.3m)^2=216.42m^2$

CIRCUMFERENCE:

$C=2\pi (8.3m)=52.15m$
