Answer:
B (2)
Step-by-step explanation:
The formula for circumference of a circle is C=2piR
Replace R with 2
C=2pi(2)
C=12.5664
Formula for area of a circle is A=piR^2
A=pi(2)^2
A=12.5664
20 minutes is
of an hour (60 minutes).
Stan's constant rate is r miles per hour, which means he drove r miles in 60 minutes. So how many miles did he drive in 20 minutes? As explained in the first line, 20 minutes is
of an hour. Since his rate is constant, Stan would drive
of what he cover in 60 minutes, which is r miles.
Hence, Stan drove
miles in 20 minutes.
ANSWER:
miles
Answer:
It would be M=-1/9
Step-by-step explanation:
You would use the slope formula:
m= y2−y1/ x2−x1
=3-4/7--2
=-1/9
