Answer: C≈628.32
Step-by-step explanation: This is due to the fact that the formula to find the circumference would be C=2πr which in this case the raduis would be 100 because if u divide the diameter by 2 u get 100. Now the formula is 2*3.14*100
To solve this problem, we know that the formula for average
speed is:
average speed = total distance travelled / total time
Now let us first calculate for the total distance
travelled. Calculating:
total distance travelled = (70 km / hr) * 2 hr + (63 km /
hr) * 5 hr
total distance travelled = 140 km + 315 km
total distance travelled = 455 km
Now for the total time:
total time = 2 hours + 5 hours
total time = 7 hours
Hence, the average speed is therefore:
average speed = 455 km / 7 hours
<span>average speed = 65 km / hr</span>
0, -1, 1.9,3,15 are irrational numbers
15x + 4 would be the algebraic expression
