[maths!]

Wait a tic, you haven't taken the square root.

 

[maths!]

yeh i did i did the square root of 120/3.142= 38.19223425

 

[Unco]

Not quite.

120/3.142= 38.19223425 is true

You then have to square root 38.19223425, preferably having it already on your calculator from the previous calculation.

Hello, maths!

A circle has a circumference of 120cm.
What is the radius of the circle?

WHOA !!

The circumference of a circle is: .C .= .2πR

We are given: .C = 120

. . We have: .2πR .= .120
. . . . Hence: . . .R .= .120/2π .≈ .19.1 cm
