I’m stuck on a maths question, pls help
“ the region R shown shaded in the diagram, is the region between two circles with the same centre.
The outer circle has radius (2n + 6)
The inner circle has radius (n-1)
All measurements are in centimetres.
The area of R is greater than the area of a circle of radius (n+13) cm
N is an integer
Find the least possible value of n
N=
5marks”
