Find the area of the circle (pi x r x r) r = 8 as it is half a diameter so in your calcu;ator press, pi * 64 then divide by 2

1/2pi*64=32pi

mean any sector of the circle?
anonymous
  • anonymous
yes

Well you will need to know the angle at the centre. This is then a ratio to 360 degrees which is then multiplied by pi r squared
anonymous
  • anonymous
area of a sector =1/2r^2*central angle
anonymous
  • anonymous
the measure of the angle is 45
anonymous
  • anonymous
angle is theta (we use this for any unknown angle)/ 360 multiplied by pi r squared.
anonymous
  • anonymous
45/360 * pi r*-r
anonymous
  • anonymous
pi r squared that should say

Is that clear? I am assuming you have been taught this method of finding the area of a triangle
