Answer:

27.19 Minutes

Step-by-step explanation:

So the Circumference is C = 2 $\pi$ r

C = 2· $\pi$ ·67.5 (the radius)

C ≈ 424.12 metres (rounded to nearest hundredth)

Then you take 424.12 metres and divide it by 0.26 metres (because it is 0.26 metres per seconds) (I like to make this weird table, I don't know how to describe it, you could do it like: $\frac{424.12 metres (times) 1 second}{0.26 metres}$ (I learned this table from chem, so let me know if you know what kind of table I'm talking about... Its a conversion table...)

The metres cancel out and you end with seconds

You end up getting 1631.23 (rounded to nearest hundredth) seconds. Divide that by 60 (seconds) and you'll get 27.19 (rounded to nearest hundredth) minutes

DIA [1.3K]

Answer:the relative ages of the rocks exposed in the circle cliff area are given below.

1. older rocks are exposed in the center and younger rocks in the flanking flatirons.

2. younger rocks are exposed in the center and older rocks in the flanking flatirons.

Step-by-step explanation: this is because whenever older rocks are exposed in circle cliffs, exposure occur at the center while younger rocks will be exposed in the flanking flatirons at this time.

2. But when younger rocks are exposed in contrast to the older rocks, these younger rocks are exposed at the center while the older ones receive exposure at the flanking flatirons.

Note that both cases interchange, exposure of a particular rock occur at the center and the next category of rock receive theirs at flanking flatirons.
