The Formula would be A=3.14rr
Which is A=3.14(3)(3)
The answer is 28.26
9000mm
because there is ten mm in one cm
They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25
16 is 4 bc 4(4) is 16
9 is 3 bc 3(3) is 9
1 is 1 bc 1(1) is 1
& so on & so forth
EXPLANATION:
To find the value of y when x is equal to 1 I must follow the following steps:
1-Replace in the given equation in the variable x by the value of 1
2.Then I must perform the operation correctly.
The exercise is as follows:
Answer:
Length of the rectangle is 18 ft when its width is 4ft
Step-by-step explanation:
Let us assume that the length is represented by l.
Let us assume that the width is represented by w.
As given
The length of the rectangle varies inversely with its width.
Thus
L x 1/w
l=k/w
Where k is the constant of proportionality .
As given
If the
length of the rectangle is 6 feet when the width is 12 feet,
l=6, w=12
putting the values in l = k/w
6 = k/12
k = 12 x 6
k=72
As given
width is 4ft
k= 72, w = 4
Putting the values in, L = k/w
L= 72/4
L=18 ft
Therefore the length of the rectangle is 18 ft when its width is 4ft
Hope this helps You
