Answer: 9 $\pi$ , or more specifically, 28.26, or even more specifically, 28.2643.

Explanation:

To find the area of a circle, you need to do r squared x pi. Since pi repeats randomly infinitely, we are going to simplify it to 3.14. 3 squared or 3 x 3 equals 9. 9 x 3.14 = 28.26. Therefore, the area of the quarter is 28.26. If you want to find the answer without simplifying pi, it is approximately 28.2643. You can also write it as 9 $\pi$ .

Answer:

I = 60 + 18k

Step-by-step explanation:

Data provided in the question:

The function for number of loaves, N that Moses bake

⇒ N(k) = 10 + 3k

here,

k is the kilograms of floor received

and,

Income in dollars, I(x) = 6x

here, x is the number of loaves baked

thus,

when k kilograms of flour is received,

x = N(k) = 10 + 3k

substituting x in income function,

we get

I = 6(10 + 3k)

I = 60 + 18k
