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 :)

Answer:

x^2 -10x+2

Step-by-step explanation:

(3x^2 - 11x - 4) – (x – 2) (2x + 3)

FOIL

(3x^2 - 11x - 4) – (2x^2-4x+3x-6)

Combine like terms

(3x^2 - 11x - 4) – (2x^2 -x-6)

Distribute the minus sign

3x^2 - 11x - 4 – 2x^2 +x+6

Combine like terms

x^2 -10x+2

Do 14 x 2/7 which is 4

Do 7 x 2/7 which is 2

then add (-7+4,-4+2) which is (-3,-2)
