Answer:
The graph will be three units lower
Step-by-step explanation:
The graph will be three units lower
A=4πr^2
A=4π12^2
12 ^ 2 = 144
4 * 3.14 = 12.56
12.56 * 144 =1808.64
(Google states it 1809.56 though...)
Answer: Xn = n(n+1)/2
Step-by-step explanation:
Firstly, you work with asingle dot for each and let n= 1,2,3,4....
Now if you double the dots, it will form a rectangle and it is easier to work with many dots i.e just multiple n by n+1
Dots in rectangle= n(n+1)
But remember the number of dots were doubled therefore,
Dots in triangle = n(n+1)/2.
I wonder what shape the window is? It has a radius so I expect a circle but you use the word perimeter which is usually reserved for shapes with sides.
So my guess is you are looking for the circumference of a circular window with radius 20. The circumference is given by (pi)d where d is the diameter. The diameter is twice the radius so 40. We use 3.14 to approximate pi.
That makes the circumference (the distance around the circle) = (40)(3.14)=125.6
