The Basics
What is a composite figure?
A figure made from two or more geometric figures (or shapes).
"double points" What is the area of a sector?
a=pi x radius x radius x angle
360
A figure composed of two rectangles. Rectangle one has a base of 6 and a height of 4. Rectangle two has a base of 5 and a height of 4. Find the area.
What is 44?
what is the perimeter of the rectangle with an area of 24m sqaured and one side measures 4m.
perimeter = 20m
using pythagoras theorem find the hypotenuse for a triangle if the other two sides measure 3m and 4m.
5m
How do you know if a figure is composite?
If it is made up of two or more geometric figures or shapes.
What is formula for pythagoras theorem
A figure is composed of a square and a triangle. The length of each side of the square is 4. The base of the triangle is 4 and the height is 7. Find the area.
What is 30?
What is the first step in finding the area of a composite figure?
Separating the figure into simpler figures
or
finding the missing sides first.
"Double points" Using sin trig ratio.. if the hypotenuse is 7m and the base is 4m. what is the angle.
34.8 degrees
35 degrees
How do you find the area of a composite figure?
Find the area of each figure and add them together.
A figure is composed of a rectangle with two triangles on each end. The base of the rectangle measures 3 and the height measures 2. The base of EACH triangle is 2 and the height of each triangle is 6. Find the area. Picture will be drawn.
What is 18.
!!DAILY DOUBLE!! Martina designed a painting on a canvas for an art project. The painting consists of 4 large circles with a radius of 6 inches. What is the total area of all four circles.
452.16 inches squared
to find the hypotenuse when you have the angle and the adjacent side. which trig ratio would you use.
COS or CAH
True or False? A composite figure must have an even number of sides?
False
What is the area of a circle?
pi r squared
The radius of the semi-circle is 6mm. Find the area.
What is 56.52 or 56.5 or 57
Mrs. Watson has two whiteboards in her room. One is 3 ft. wide and 8 ft. long. The second is 4 ft. wide and 7 ft. long. What is the total area of the shape?
52 squared ft.
opposite side = 10cm and angle is 53 degrees. what trig ratio would you use
SIN or SOH
True or False? A composite figure can have a maximum of 3 shapes.
False
What is the area of a semi-circle?
pi r squared divided by 2
which area is larger a circle with a radius of 8m or a triangle with a base of 20m and a height of 6m.
What is area of circle
what is the angle of the triangle if the opposite side = 12cm and the adjacent side = 10cm. rounded to a whole number.
50
