I'm confused once again. Circle Circumference of 60cm. Calculate the area of a Quadrant of that Circle. So I know a Quadrant is a quarter of a circle. So I first calculate the area of the circle. A = Pir^2 3.14 x 30 x 30 = 2826, then I divide by 4 to get quarter = 706.5cm^2 But in my text book it says the answer is... 71.63 cm^2 I just realized that I was looking for a diameter not circumference. My mistake. I figure it out I just did A = C^2 / 4 pi then divided by 4. All good. Last edited by skipjack; November 5th, 2016 at 03:32 PM.

The answer should be 71.62 cm² (after rounding to 4 significant figures).

Hint We know circumference $\;\;C=2\pi r$ calculate $r$ from this Area of a quadrant = Area of quarter of circle $=\dfrac{\pi r^2}{4}$
