If the area of a circle is7.7 cm2, what is the
circumference of the
circle? (I need a step-by-step answer for further understanding please!!)

Answers

Answer 1
Answer:

Answer:

Since area =7.7

area = (22)/(7) {(r)}^(2) \n {(r)}^(2) = 2.45 \n r = 1.57

Then the circumference is

c = 2pi* r \n = 2 * 3.14 * 1.57 \n = 9.859

When multiplying a term (either constant or variable) by a quantity in parentheses, we multiply each term inside the parentheses by that term. So 5 times x minus 5 times 6.

A share of stock in the Lofty Cheese Company is quoted at 25 1/4. Suppose you hold 30 shares of that stock, which you bought at 20 1/4. If you sell your stock at 25 1/4, which one of the following statements would be true? A: you'll suffer a loss of $15
B: you'll make a profit of $15
C: you'll make a profit of $150
D: you'll suffer a lose if $150

Answers

Since each share was purchased when it was still quoted at 20 1/4, then when the stock value increases, it gains (25 1/4 - 20 1/4) = $5.00 for each stock.Since you're to sell 30 shares of your stock, that means you'll be making a profit of (30 x 5 ) = $150.00.Thus, the answer is C.

The true statement is that you'll make a profit of $150 which is option C.

Given that,

A share of stock in the Lofty Cheese Company is quoted at 25 1/4.

Suppose you hold 30 shares of that stock, which you bought at 20 1/4.

If you sell your stock at 25 1/4, we have to know if they suffer profit or loss and by what amount.

Cost of the stock which you bought is,

Cost = 30 × 20 1/4

        = 30 × 20.25

        = 607.5

If you sell your stock at 25 1/4,

Selling price = 30 × 25 1/4

                     = 30 × 25.25

                     = 757.5

Difference = 757.5 - 607.5

                  = 150

Hence you have a profit of $150.
