The approximate radius of the circle in feet is 14.5
Solution:
Given, a tile artist is placing tiles in a circular mosaic pattern and the area of the circle is 658 square feet,
We have to find what is the approximate radius of the circle in feet?
The area of a circle is found with the formula
where "y" represents 3.14 and r is radius. So now, according to given information,
Hence, the radius of the given circle is 14.5 feet approximately
Answer:
Q matches to a and P matches to b
Step-by-step explanation:
This is a volume question so we can use the volume of a cylinder to see which one corresponds to what. Volume of a cylinder is h. We know that the heights of the cylinders are the same since the diagram says so. We also know pi is the same since thats a constant. The only thing thats different is the radius (as you can see radius of P is bigger than Q). If the radius of P is bigger than Q and all the other things are the same (height is the same and pi is the same), then that automatically means that P has more volume than Q. More volume means more time to fill up. Since Q has less volume, it will take less time to fill up. So now we look at the graph. A shows that the height of water increases at a faster rate than that of B. This is because there is less volume in that container (less volume=less time to fill up). Therefore a matches to Q and therefore b matches to P
