Answer 2 maths questions please?

1) Use a proportion angle of sector / angle of circle = area of sector / area of circle Let x = area of sector 90/360 = x/(pi3^2) 1/4 = x/9pi x = 9pi/4 = 7.069cm^3 2) Use a proportion to find the length of arc PQ angle of arc / angle of circle = length of arc PQ / circumference of circle Let x = length of arc PQ 90/360 = x/(2(3)pi) 1/4 = x/(6pi) x = 6pi/4 = 4.712 sector POQ's perimeter = 4.712 + PO + QO = 4.712 + 3 + 3 = 10.712cm.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
