As shown in the following figure, the radius of a circle is 1 cm, and it circles a round around the right trapezoid. What’s the total distance the centre O goes? (AD=5cm,BC=8cm,AB=6cm,CD=8cm) 相关知识点: 试题来源: 解析 [解析]圆心O走的路程就是梯形的四条边和一个半径是1厘...
There's no way to figure out the area of the shaded region directly, but you can figure out the area of the non-shaped region and subtract. Since the radius of the circle is 5, you know that the area of the circle is 25π. Subtract that from the area of the square, 100, to g...

You can see that the area of the shaded region is just the difference of the area of the big circle (radius b) and the area of the small circle (radius a). The area of the small circle is just a^2, and the area of the big circle is just b^2. So the difference is:π b^...
