Answer:

49π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 14, so r = 14 ÷ 2 = 7, then

A = π × 7² = 49π cm²

Answer:

49pi cm^2

Step-by-step explanation:

$a = \pi \: {r}^{2}$

Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7

A = pi × 7^2

A= pi × 49cm^2

Janine wants a necklace 45 beads long

seraphim [82]

If there are 45 beads, with a ratio of $1:4$
Then,
$\frac{45}{5}=9$
Then if $\frac{1}{4}=\frac{9}{x}$
Then $x=9*4$
Therefore, $x=36$
Meaning, there would be a ratio of 36 beads to 9 beads

four time the first of three consecutive integers is six more than the product of two and the third integer. find the integers.

maw [93]

<span>
Assign variables :
Let x = first consecutive even
Let x + 2 = second consecutive even
Let x + 4 = third consecutive even
4x = 6 + 2(x+4)
4x = 6 + 2x + 8
4x = 2x + 14
4x - 2x = 14
so your answer is 7,9and 11</span>
