Answer:
In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.
Step-by-step explanation:
Answer:
150 pi inches or 471.239 inches traveled
Step-by-step explanation:
First, close your eyes, and think about the distance a bike travels after one rotation of the wheel.
You will come to the realization that a full rotation of the wheel makes you travel the circumference of the wheel
The formula for circumference is 2(pi)(r) or (pi)(diameter)
We are given diameter, so let's find distance traveled for one rotation
pi(15 inches) = 15pi inches per rotation.
There are 10 rotations, so:
(15pi inches/rotation)(10 rotations) = 150pi inches travelled
150 x pi = 471.239 inches traveled
You add the two numbers and divide them by two
8 * 2 * 10 = 160 * 10 = 1600
1. 2.50x + 5 = C
2.50(4.1) + 5 = C
$15.25
2. 15.25(1.15)
$17.54
3 B, I believe but dont quote me.
4. 206 / 60 + 30
236 minutes
