C2 - Radian QsMay I please have help with these questions? (I know, I'm probably in the forum pretty much every day...)
1.)I have to calculate the area of the shaded region.
I figured out L:
L=rθ
=3.6(2/3π)
=12/5π=BC
2.) An arc subtends an angle of 0.25 radians at the circumference of a circle, centre O and radius 6cm. Calculate the area of the minor sector OAB.
With this, I just have difficulty visualising the diagram. -
