Question

I need help with this i cant cuaet understand this Find the radius given the diameter

Answer 1

Given the diameter of a circle, we can find its radius by dividing the diameter by 2, like this:

`r=(d)/(2)`

Where r is the radius and d is the diameter of the circle, by replacing 30 for d, we get:

`r=(30)/(2)=15`

Then, the radius of this circle equals 15 m
