X=7 and y=-13 so 7 and-13
Area= pi*r^2
So since the radius is half of the diameter, you need to divide 40/2=20
radius = 20
pi*20^2
20^2=400
pi= 3.1415...
pi*400=1256.63706...
So area will equal =1256.63706..., (since pi is never ending)
{ I might be wrong.]
21 22 23 24 25 26 are the whole numbers
This is the concept of numbers, given that the radicals sqrt2 and sqrt3, what we can deduce from the two radicals is that they are both like terms. This is because, they don't make perfect squares now that there are no integers such that x*x=sqrt 2 or x*x=sqrt3.
They are also not equal to each other because, 2 ≠ 3
