Answer:
Pattern seen is arithmetic progression. The both equations are same.
Step-by-step explanation:
a.The given pattern is 8,12,16,20,24....We can see that the difference between any two consecutive terms is 4.Therefore this is an AP(arithmetic progression).
b.Percy's equation ,
⇒
⇒
⇒
which is the same as Stella's equation . So , we can see that both equations are the same.
Answer:
<h2>71.8%</h2>Step-by-step explanation:
The shape described in question is a square overlaid with two quarter circles(a semi circle)
Area of the figure = Area of the square + area of the semi circle
Area of the figure =
L = length of a side of the square = 12in
r is the radius of the semi circle = 6in
Area of the figure =
Area of the figure = = 200.55in²
Since the shaded portion is a square;
percent of the total area is shaded = area of the square/total area * 100%
percent of the total area is shaded = 144/200.55* 100
percent of the total area is shaded= 71.8%
