A quadrant is a quarter of a circle. So, to work out the area of a quadrant, first work out the area of the whole circle (use the formula A = π×r²) and then divide the answer by 4. Alternatively, you could substitute the radius of the quadrant directly into the formula A =...
Figure 13 – Quadrant of Circle Example Solution In Figure A,there aretwo radii ADandAE. We can see that they arenot right anglesto each other rather they are at somewhat60 degreesto each other, moreoverAEDisnotone-fourth portionof the whole circle so we will conclude thatAEDisnotaquadra...

We are asked to find the area between two curves. We will use the formula for area: A=∫abydx To calculate the net are, will take the area of the outer curve (y2) and then subtract the area of the inner curve (y1): A=∫ab(y2)dx−π∫ab(y1)dx...
15° is not a commonly known angle, and it doesn't usually appear on the unit circle. But 15 is half of 30, which is a common angle on the unit circle. Use the half-angle identity for sine. $$sin\:15^{\circ}=\sqrt{\frac{1-cos\:30^{\circ}}{2}} $$ ...
