Answer:
Area = 
square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
Step-by-step explanation:
As we know the circumference of a circle is 
The radius of the hub cap needs to be devised to determine the area
centimeters
Area of the hub cap = 
Substituting the devised value of r in the above equation, we get -
square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
Answer:
9/4
Step-by-step explanation:
When you divide by a number, whole number or fraction, it's exactly like multiplying by its inverse.
Like if you divide 4 by 2, you can easily express that has 4 * 1/2.
In the same manner, when you divide 3/4 by 1/3, you can say that you're multiplying 3/4 by 3/1
The result of 3/4 * 3/1 = 9 / 4
Which you cannot simplify because 9 and 4 don't have any common factors (other than 1). The only other way to express it would be 3²/2² or (3/2)²
