Answer:
Using the concept of speed-distance-time, we find that the diameter of the circular path is 12 inches.
Step-by-step explanation:
Given that the object completes one revolution in 8 seconds. So, the circular speed of the object is 2πr/8 = πr/4 inches per seconds, where r is the radius of the circular path. The speed can be written as:
πr/4 inches per seconds = 60πr/4 inches per minute = 15πr inches per minute.
But, it is given that the circular speed of the object is 90π inches per minute. So,
90π = 15πr
r = 6 inches
Since, diameter is the double of radius, d = 2r = 12 inches.

Answer:
1st number = 17
2nd number = 18
Step-by-step explanation:
Unknown number = x
Since they are consecutive numbers, we add 1 to each other.
=> x + x + 1 = 35
=> 2x + 1 = 35
=> 2x + 1 - 1 = 35 - 1
=> 2x = 34
=> 2x/2 = 34/2
=> x = 17
So, the first number = x = 17
=> Second number = x + 1 = 17 + 1 = 18
1st number = 17
2nd number = 18
