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

Could someone check my answer please . Thank you

Hello! We will be using the Pythagorean theorum, where a² + b² = c². C is the clanted part of the triangle, and 13² is 169. a = 12, and we are looking for the value of b. 12² is 144. Let's subtract to find b. 169 - 144 is 25. Now, let's find the square root of 25 to find the length. √25 is 5. There. b = 5. The side length of side b is 5. The correct answer is C: 5.

Jebb is the tallest player on the basketball team. He is 1 1/2 times as tall as the shortest girl in the sixth grade, who is 4 1
Tom [10]
So to get this, we multiply 4 1/4 by 1 1/2 because he is 1 1/2 times taller than her. 4 1/4 x 1 1/2 = 6 3/8 feet tall. 
Hope this helps!

What is the surface area of a cylinder whose base radius is 7 cm and whose height is 8 cm?
Mnenie [13.5K]

Answer:

659.73

Step-by-step explanation:

i searched up surface area cylinder calculator to get the answer but incase u can't use that

A= 2(pi) r h + 2 (pi) r ^2

in this case it would be

A= 2 (pi) (7) (8) + 2(pi) 7^2

after that u should be able to get 659.73

if u didnt understand the explanation try searching up "surface area cylinder calculator" and it should pop up!

(my fault if the answer is wrong btw)
