If the diameter is 30 ft then the area of the circle is 706.5 you can approximate it if you want and you will have 707.

(x - h)^2 = 4p(y - k)

(-1 - 3)^2 = 4p(8 - 0.5)

(-4)^2 = 4p(7.5)

16 = 30p

p = 16/30

p = 8/15

(x - 3)^2 = 16/15(y - 0.5)

15(x^2 - 6x + 9) = 16y - 8

15x^2 - 90x + 135 = 16y - 8

16y = 15x^2 - 90x + 135 + 8

y = 15/16 x^2 - 90/16 x + 143/16

f(x) = 15/16 x^2 - 90/16x + 143/16

Answer:

$\displaystyle 4536,4597918...\:cm.^2 = A$

Step-by-step explanation:

Split the diametre in half before proceeding:

$\displaystyle \pi{r}^2 = A \\ \\ 38^2\pi = A \hookrightarrow 1444\pi = A \\ \\ \boxed{4536,4597918... = A}$

uranmaximum [27]

To find the total cost, you need to add these numbers together

$1.89 + 3.19 + 2.29 = 7.37$
you get 7.37 as your answer, but you need to round this to the nearest whole number.

rounding 7.37 will make it 7.

the total cost is about $7
