Answer: a) 24, 47.88017308
b) 23.88017308.
Explanation:
STEP ONE:
We know the formula for calculating the diameter is to multiply the radius by 2. But since we don’t have the radius figured, let’s do so:
Divide your circumference by Pi, or aka 3.14
So 75.36 divide by 3.14 = 24
So the diameter for Week 1 is 24.
STEP TWO:
Basically you follow the same steps shown above for Week 2.
So, 150.42 divide by 3.14 = 47.88017308
Oof, that’s not a very nice number, isn’t it?
Kay. Now we have to figure out how many times greater Week 2’s diameter is than Week 1.
I did: 47.88017308 - 24 = 23.88017308.
So, Week 1’s diameter is roughly 2 times greater.
Hope this helped :)
