How do you find the area of a circle and what is the formula for it
2 answers:
Answer:
formula is πr² ( pi x radius squared)
Step-by-step explanation:
the value of π is 3.142...
multiply this value with the squared radius of the circle and you'll get your answer.
For example:
we have a circle with diameter 5
so, π x 5² = 3.142 x 25 = 78.5
Answer:

Step-by-step explanation:
Area = 3.14 x r^2
I've Included a picture to tell you how to get the diameter as well as the circumference.

Answer:
Step-by-step explanation:
y = 4 + 6x
Let x = 1
y = 4 + 6(1)
y = 4 + 6
y = 10
Let x = 5
y = 4 + 6*5
y = 4 + 30
y = 34
Let x = 6
y = 4 + 6x
y = 4 + 6*6
y = 4 + 36
y = 40
Let x = 10
y = 4 + 6*10
y = 4 + 60
y = 64

I think any irrational number would do this? I'm not positive though. Some examples may be pi or the square root of 2.
That is dependent because it is changing.independent stays the same
