Area=πr^2
find the area then divide by 8
we know that diameter=2radius or diameter/2=radius so
12=diameter
12/2=radius=6
subsitute
area=π(6)^2
area=36π
divide 36π by 8
36π/8=18π/4=9π/2π=4.5π
area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
9514 1404 393
Answer:
9n^4
Step-by-step explanation:
The divisor and quotient can be interchanged to find the divisor:
![\dfrac{18n^6+27n^5-36n^4}{2n^2+3n-4}=\boxed{\text{Blank 1}}](https://tex.z-dn.net/?f=%5Cdfrac%7B18n%5E6%2B27n%5E5-36n%5E4%7D%7B2n%5E2%2B3n-4%7D%3D%5Cboxed%7B%5Ctext%7BBlank%201%7D%7D)
Such division is carried out by first finding the quotient of the highest-degree terms:
![\dfrac{18n^6}{2n^2}=\dfrac{18}{2}n^{6-2}=9n^4](https://tex.z-dn.net/?f=%5Cdfrac%7B18n%5E6%7D%7B2n%5E2%7D%3D%5Cdfrac%7B18%7D%7B2%7Dn%5E%7B6-2%7D%3D9n%5E4)
This value is used to multiply the denominator and subtract that product from the numerator to find the new numerator. The new numerator is zero, so the value that goes in Blank 1 is ...

_____
The attachment shows the long division.
Answer:
54.6
Step-by-step explanation:
42 = 70%
100% - 70% = .30%
42 x 1.3 = 54.6
Answer:
3/2
Step-by-step explanation:
formula k = y/x
comes from
y = kx
k = constant of variation
when y = 3 , x = 2
k = 3/2
