Triangles have 3 vertices. The total is 21 vertices. 21 / 3 = 7. He drew 7 triangles.
<span>The
graph of y against x in inverse proportion is a rectangular hyperbola
but I don't see at all how this knowledge/observation is any help in
solving the problem.
Inverse proportion means that as x doubles y will halve and the equation
is xy = k where k is some number. A good example of inverse proportion
is speed and time taken over some fixed distance. In this case x could
represent the speed (mph) and y the time (h) and then k is the distance
in miles.
Since we know y=3 when x=2 we have xy = 6. Now it's easy to see when x=6 y=1.</span>
Answer:
5.8 cm
Step-by-step explanation:
Area of the shaded sector of the circle = 31.2 cm²
Angle (θ) of the minor sector = 360 - 256 = 104°
Are of sector of a circle is given as, θ/360*πr²
Therefore:



Divide both sides by 0.91




(nearest tenth)
