Question

Find the circumference of a circle witha radius of 3 units..
A) 9.42
B) 20.1 units
C) 18.84 units
D) 15.94 units

Answer 1

\(\Large \color{MidnightBlue}{\Rightarrow Circumference = 2\pi r }\)

Answer 2

Here, it'd be
\(\Large \color{MidnightBlue}{\Rightarrow 2 \times 3.14 \times 3 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 6 \times 3.14 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 18.84 units}\)

Answer 3

I believe it's C

Answer 4

Yes!

Answer 5

Oh, yes

Answer 6

C = Circumference r = radius π = approximate value 3.14 So just plug things in. C = 2(3.14)(3)

Answer 7

Exactly
