Quantity A Length of AO Quantity B Length of AB
AB is a diameter of the circle above. Quantity A The length of AB Quantity B The average (arithmetic mean) of the lengths of AC and AD
If the difference between the radii of two concentric circles is 5, then what is the difference between their perimeters?
The figure above shows a rectangle inscribed in a large circle. Inside the rectangle is a small circle of radius 2 that is tangent to two sides of the rectangle. If the length of the rectangle is twice its width, what is the area of the large circle?
A square hole with a side of 1 foot needs to be totally covered by the base of a hemisphere. What`s the least length of the radius of the hemisphere?
In a circle, the area of the shaded sector is 16π. Quantity A The radius of the circle Quantity B 5.5
The area of the shaded area is 12π. The smaller circle intersects with the bigger one at one point and passes through the center of the bigger circle. What is the diameter of the smaller circle?
The radii of the above two circles are both 3. If these two circles intersect at point P and point Q and each circle pass through the center of the other circle, then what is the total perimeter of the region (not counting the arc inside)?
If the area of the square is 196, when what is the area of the shaded area?
Each of the four semicircles shown in the figure has a side of the square as its diameter and has exactly one point in common with the larger circle. If each side of the square has length 4,what is the sum of the areas of the shaded regions?
Four same circles with a radius of 4 are inscribed in a larger circle. What's the area of the larger circle?
The figure above shows a rectangle and five circles. Each circle is tangent to the other circles and to the sides of the rectangle that it touches. If the diameter of each circle is 4, what is the area of the rectangle?
Quantity A: x Quantity B: y
Quantity A: AB Quantity B: BC
A triangle is inscribed in a semi-circle with a radius of r Quantity A: $$x^{2}+y^{2}$$ Quantity B: $$4r^{2}$$
The length of each side of a smaller cube is 2. What is the surface area of the bigger cube formed out of 125 such cubes?
A gardener plans to cover a rectangular plot of land with pine bark mulch to a depth of 4 inches.The plot measures 8 feet by 12 feet, and the gardener will buy mulch packed in bags. If each bag contains 3.5 cubic feet of mulch and costs $6,what is the cost of the least number of bags that the gardener will need to cover the plot? (Note: 1 foot=12 inches.) ______dollars
For the rectangular solid below, find the following. What is the surface area of the solid?
In the rectangular solid above, TU=3, VU=4，and VR=2. What is the area of the shaded rectangular region?
A rectangular solid box has a height, width and length ratio of 1:2:3 and a surface area of 550. What is the volume of the box?
