Hi guys, in this exercise we are going to execute the area for this circle. So let’s
start up the formula for the area – okay, they are asking for R for radius and we do
not have radius we have diameter which is from one edges all the way the other edges
18mm we need to half that in half just to get the radius. So let us do that now –
so our radius half of 18mm is 9mm, now we can take that value and plunk it into the
formula where it is need to be R squared so let us work the area for this circle –
so our pi again is 3.14 x 9 squared which is the radius our total and complete area
right here in flora vivid yellow is – 254.5mm.
