Question

what is the formula for finding radius of a circle

Answer 1

if you are given the diameter then formula will be... d/2

Answer 2

hi dear friend

we can find radius of circle in different ways depending upon the data given in the question

for example

if they given circumference of circle then use the formula ( 2 pi r ) to get dadius

if they given area of circle then we can use the formula ( 2 pi r^2 )

if the diameter is given then radius is d/2

these are the 3 formulae which we use most probably

well at last i want to say that

according the the given data only we can find the radius of circle
