Answer:
C=37.68
Step-by-step explanation:
The radius is 6ft.
The diameter is 2x of the radius.
6*2 = 12 = diameter
Now, we can plug in 12 in the equation C= 3.14d
C=3.14*12
C=37.68
There is a great website called Desmos. You can enter any equation and it wil graph it for you.
Answer:
first count the number of decimal places in the base number, as when multiplying decimals (see Decimal Multiplication. Next, multiply that number by the exponent. This will be the total number of decimal places in the answer.
Step-by-step explanation:
Answer: option a. 5.46
Explanation:
The side lengths of the golden rectangle are in the proportion:
1
--------------------
golden number
The golden numbrer is:
1 + √5
-----------
2
So, the ratio is:
1
--------------
1 + √5
---------
2
And, using the properties of the division of fractions, that is equivalent to:
2
-------------
1 + √5
Since you have the given side t = 9, you can set the proportion, to find the unknown lenght, s:
2 s
--------- = ---------
1 + √5 t
2 s
--------- = ---------
1 + √5 9
And you can solve for s:
s = 9 * 2 / (1 + √5) ≈ 18 / (1 + 2.236) = 18 / (3.236) ≈ 5.56.
Which is the option a. 5.56
