Answer:


Step-by-step explanation:
We are asked to find the circumference and area of a circle with a radius of 3 meters.
<h3>1. Circumference </h3>
The circumference is the perimeter of a circle. It is calculated using the following formula:

We know the radius of the circle is 3 meters, but we must find the radius. The radius is the line from the center to the circle's edge, while the diameter is the line through the center from edge to edge. Therefore, the diameter is twice the radius.
The diameter is 6 meters and we are using 3.14 for pi. Substitute these values into the circumference formula.

Multiply.

<h3>2. Area </h3>
The area is the size of the circle's surface. It is calculated using the following formula.

The radius is 3 meters are we are using 3.14 for pi. Substitute these values into the area formula.

Solve the exponent.
- (3 m)² = (3 m)(3 m)= 9 m²


The circumference is 18.84 meters and the area is 28.26 square meters.
It would be biased because one would assume that students can get to school by means other than those that put them 8n the parking lor. (Parking lot = car drivers who would be the only students sampled.). Others may ride to school by either parent or school bus who could drop them off somewhere else or possibly walk to school. The freshmen/sophomores would be excluded generally as they would be too young to drive altogether
