Question 1

The circumference of a circle is 6.28 millimeters. What is the circle's diameter?

plsssss i need help!!!!!!!!

Question 2

the diameter would be 2. i hope this helps!

Question 3

Ⲁⲛ⳽ⲱⲉⲅ:

$\quad{\rule{300pt}{1.5pt}}\quad$

Ⲋⲟⳑⳙⲧⳕⲟⲛ :

We are given that :

We know that :

$\qquad\bull{\boxed {\mathfrak{Circumference = 2 \pi r }}}\bull$

Therefore,

$\quad\dashrightarrow\quad \sf { 6.28 = 2 \pi r }$

$\quad\dashrightarrow\quad \sf {r = (6.28)/(2\pi) }$

$\quad\dashrightarrow\quad \sf {r = (6.28* 7)/(22* 2) }$

$\quad\dashrightarrow\quad \sf {r =\cancel{(43.64)/(44)} }$

$\quad\dashrightarrow\quad \sf {r = 0.9989 }$

As we know,

$\quad\dashrightarrow\quad \sf { Diameter = 2* radius}$

$\quad\dashrightarrow\quad \sf { Diameter = 2* 0.9989}$

$\quad\dashrightarrow\quad \sf { Diameter = 1.98 }$

$\quad\dashrightarrow\quad {\pmb{\sf {Diameter = 2 mm ( approx ) }}}$

$\rule{300pt}{2pt}$
