A circle has a radius of 30 cm. What is that circumference of the circle?

C = 60pi cm or approximately 188.4 cm

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

C = 2* pi * 30

C = 60 pi

We can approximate pi by 3.14

C  is approximately 60*3.14 or 188.4

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
