a) So we know the formula of finding the circumference: 2*pi*R.
Assuming we make pi = 3.14: 2 * 3.14 * 7 = 43.96.
b) We also know the formula of finding the area: pi * r^2.
3.14 * 7^2. Using PEMDAS:
3.14 * 49 = 153.86
Answer: 4 hrs
Step-by-step explanation: D=RT
500=(65+60)T
500=125T
T=500/125
T=4 HOURS THEY'L MEET.
Answer:
14 burgers
Step-by-step explanation:
3 1/2 ÷ 1/4 = 14
Answer:
D
Step-by-step explanation:
|C|<|D|
So C≠D
It would help if you had a four quadrant graph, but the distance would be (8,11).
