Answer:

C ≈ 14.18

Step-by-step explanation:

<u><em>Question Given:</em></u>

A circle has an area of 16mm². Find it's circumference.

<u><em>Formula:</em></u>

C = 2√πA

<u><em>Solve:</em></u>

C = 2√πA

C = 2√(3.14 × 16)

C = 2√50.24

C = 14.1760361173

C ≈ 14.18

<em>Hence, Circumference is approximately 14.18.</em>

{ \qquad\qquad\huge\underline{{\sf Answer}}}

Here we go ~

Area of Circle :

\qquad \sf  \dashrightarrow \:  \pi {r}^{2}

Now, it's given that area of circle is : 16 mm²

Let's calculate Radius ~

\qquad \sf  \dashrightarrow \: \pi {r}^{2}  = 16

\qquad \sf  \dashrightarrow \:  {r}^{2}  =  \cfrac{16}{ \pi}

\qquad \sf  \dashrightarrow \: r =  \sqrt{ \cfrac{16}{ \pi} }

\qquad \sf  \dashrightarrow \: r =  { \cfrac{4}{ \sqrt{ \pi} } }

Now,

\qquad \sf  \dashrightarrow \: circumference =  2\pi r

\qquad \sf  \dashrightarrow \: c = 2 \pi  \cfrac{4}{ \sqrt{ \pi} }

\qquad \sf  \dashrightarrow \: c = 8 \sqrt{ \pi}

[ for approximate value take pi = 3.14 ]

\qquad \sf  \dashrightarrow \: c = 8 \sqrt{3.14}

\qquad \sf  \dashrightarrow \: c   \approx 8 \times 1.77

\qquad \sf  \dashrightarrow \: c   \approx 14.18 \:  \: mm

Each side of a square is increased by 3 inches. The perimeter of the new square is 40 inches more than twice the length of the s
RUDIKE [14]

Length of side of new square is 17 inches

Step-by-step explanation:

  • Step 1: Let the length of the side of the old square be x. Then length of side of new square = x + 3 and Perimeter of new square = 40 + 2x

Perimeter of a square = 4 × side

⇒ 4(x + 3) = 40 + 2x

⇒ 4x + 12 = 40 + 2x

⇒ 2x = 28

⇒ x = 14 inches

  • Step 2: Find length of side of the new square

⇒ x + 3 = 17 inches

goldenfox [79]

Answer:

Step-by-step explanation:

6k^3+10k^2-56k\\2k(3k^2+5k-28)\\=2k[3k^2+12k-7k-28]\\=2k[3k(k+4)-7(k+4)]\\=2k(k+4)(3k-7)

common factor is 3k-7

a box of crackers has a volume of 48 cubic inches. what is the volume of a similar box that is smaller by a scale factor of 2/3
earnstyle [38]
For this case what you need to know is that the original volume of the cookie box is:
 V = (w) * (l) * (h)
 Where,
 w: width
 l: long
 h: height.
 We have then:
 V = (w) * (l) * (h) = 48 in ^ 3
 The volume of a similar box is:
 V = (w * (2/3)) * (l * (2/3)) * (h * (2/3))
 We rewrite:
 V = ((w) * (l) * (h)) * ((2/3) * (2/3) * (2/3))
 V = (w) * (l) * (h) * ((2/3) ^ 3)
 V = 48 * ((2/3) ^ 3)
 V = 14.22222222 in ^ 3
 Answer:
 the volume of a similar box that is smaller by a scale factor of 2/3 is:
 V = 14.22222222 in ^ 3
