Answer:

Step-by-step explanation:

Area of circle = π r²

r = 30

30² = 900

π = 3.14 or ≈ 3

A ≈ 900 × 3

A ≈ 2700

so C at 2830 is closest to the answer

Answer:

$1530

Step-by-step explanation:

First of all, it is required to convert 35g of gold into ounce.

Since,

1 oz = 28 g

or, we can write,

$1 g = \frac{1}{28} oz$

Now, for 35 g of gold, we can write,

$35 * 1 g = 35 * \frac{1}{28} oz\\35 g = 1.25 oz$

Since, local jewelry will buy at $ 1224 per oz, and we have 1.25 oz of gold, so,

$1.25 * 1244\\$1530$

Please simplify: −23d+81≤−98d+1

Strike441 [17]

$- 23 d + 81 \leq -98 d + 1$

Subtract 81 from both sides :

$-23 d + 81-81 \leq -98d+1 -81$

$-23d \leq -98d-80$

Add 98d to both sides:

$-23d +98 d \leq -98d-80+98d$

$75d \leq -80$

Divide both sides by 75 :

$\frac{75d}{75} \leq \frac{-80}{75}$

$d \leq =- \frac{16}{15}$

hope this helps!.
