Answers

Answer 1
Calculate the area of a circle.

To start solving the exercise, we obtain as data:

π = 3r = 3 ft

We apply as a formula:

A = πr², whereA = areaπ = pir = radius

We apply the formula and solve:

A = π r²A = 3× (3 ft)²A = 3 × 9 ft²A = 27 ft²

Therefore, the area of the circle is 27 ft².

Answer 2

Answer: 27ft²

Step-by-step explanation: Soln:

Given that,

π=3

Radius(r)=3ft.

We have,

A = π r²

A = 3* (3)²

A=3*9

A=27ft²

Aleah buys 2 DVDs for $6 and 4 CDs for $8. Her friend, Ling, wants to buy 4 DVDs and 2 CDs. How much will Ling have to pay?

Aleah's brother, Pierre, wants to spend $20 on DVDs and CDs. What combination of DVDs and CDs could he buy?

Answers

Step-by-step explanation:

If Aleah buys 2 DVDs for $6 and 2 CDs for $8 we can well assume that the DVDs are $3 dollars each and the CDs are 4 Dollars Each. If ling wants to buy 4 DVDs You would multiply how many DVDs she's buying with the price of the DVDs so (4x3=12) so Ling would have to pay $12 for the DVDs and $8 on the CDs

Pierre wants to spend $20 so with the previous information we can come to the solution that Pierre can buy 4 DVDs and 2 CDs for $20.

Answers

Answer:

If you multiply or divide both the top of a fraction and the bottom of a fraction by the same number, so for example:

[tex]\frac{2}{4}[/tex]÷[tex]\frac{2}{2} = \frac{1}{2}[/tex]

1/4 = 2/8

4/2 = 2/1 or 2

2/3 = 4/6

6/8 = 3/4

1/3 = 2/6

1/4 = 2/8

1/2 = 2/4

4/6 = 2/3

3/6 = 1/2

Answerk:

The answer is

[tex] \frac{1}{2} = \frac{2}{4} = \frac{3}{6} \\ \frac{2}{3} = \frac{4}{6} [/tex]
