This formula gives the area of a triangle.
What is A=.5bh?
This formula gives the area of a trapezoid.
What is A=.5(b1+b2)h?
This formula gives the circumference of a circle using its radius.
What is C=2πr
Two triangles with the same base and height have this relationship between their areas.
What is they have equal areas?
Geometric probability compares the ratio of favorable area to this larger area.
What is the total area?
The area of a parallelogram is found by multiplying these two measurements.
What are the base and the height?
A trapezoid has bases 8 and 14 with height 6. This is its area.
What is 66 square units?
A circle with radius 7 has this area (in terms of π).
What is 49π units squared?
If two similar figures have a side ratio of 1:3, their area ratio is this.
What is 1:9?
A point is randomly chosen inside a square of area 100. A smaller square inside has area 25. This is the probability the point lands inside the smaller square.
What is 1/4?
A rhombus has diagonals of 10 and 14. This is its area.
What is 70 square units?
The perpendicular distance from the center of a regular polygon to one of its sides is called this.
What is the apothem?
An arc measuring 90° represents this fraction of a circle.
What is one fourth?
If two similar triangles have a scale factor of 4, their areas change by this factor.
What is 16?
A dart lands randomly on a circular dartboard. This type of probability uses lengths, areas, or volumes instead of counting outcomes.
What is geometric probability?
A triangle with base 16 and height 9 has this area.
What is 72 square units?
This formula finds the area of a regular polygon using its apothem and perimeter.
What is A=.5aP?
A circle has radius 10. The arc length of a 90° arc is this.
What is 5π units?
Two triangles share the same height. Their bases are 5 and 15. This is the ratio of their areas.
What is 1:3?
A circle is inscribed in a square. This is the probability a random point in the square is inside the circle.
What is π/4?
This quadrilateral’s area can be found using the formula A=.5d1d2
What is a rhombus?
A regular hexagon has a perimeter of 36 and an apothem of 5.2. This is its area (rounded).
What is about 93.6 square units?
A sector with central angle 60° in a circle with radius 12 has this area.
What is 24π units squared?
Two similar polygons have an area ratio of 9:25. This is the ratio of their corresponding side lengths.
What is 3:5?
A square has side length 10 and contains a circle with radius 3. This is the probability that a random point in the square lies inside the circle.
What is 9π/100?
