Find the area, correct to the nearest square

Mathematics
1 answer:
Lady bird [3.3K]2 years ago

Answer:

1269 square meters

Step-by-step explanation:

The path and the plot of land form two concentric circles (they have the same center). The radius of the plot of land is 100m (half of the diameter) and the radius of the larger circle, formed by putting a 2m wide path around the plot of land, is 102m. Thus, the area of the path is \pi *102^2 minus \pi *100^2 which will be 10404\pi-10000\pi which is 404\pi. Estimate \pi to 3.141 and calculate, getting 1268.964... which is 1269, rounded to the nearest square meter.

Hope this helps :)

How many hours is between 9:30pm to 8:15am
faltersainse [42]
There are 10 hours and 45 minutes between 9:30 pm and 8:15am. We can figure this out by counting the hours in between 9:30pm and 8:15am. You would stop at 7:30 am to get 11 hours but 7:30 is not 8:15 is it? So we would need to figure out the additional minutes that we need by first adding 30 minutes to get to 8:00 then another 15 to get to 8:15. When added, 30 plus 15 equals 45.
To conclude, 9:30 pm and 8:15am are 11 hours and 45 minutes apart.
I hope this helped! :-)

What does x,y mean I have no idea
uysha [10]
On a graph, when a line is going up or down, that is y. When it is going horizontally, that is x.  So they can be used as points.  For example, if the coordinates were 3, 4, (x, y), then you would first go across 3 on the graph and then go up 4. There you would plot your point. It can also be used in equations. For example, if the equation was..
2x + 3y, and the coordinates were 1, 2, (x, y), then x would be 1 and y would be 2. In order to solve, you would plug in x and y. Hope this helps. If you could give me the brainiest answer that would be greatly appreciated.

ella [17]

Answer:

C.

Step-by-step explanation:

When you transfer 4% into a decimal, it equals 0.04, and p is the cost of a regular pizza, so you subtract 0.04 from p!
