"Formula of a circle" is too vague to be meaningful. Perhaps you meant, "Formula for the area of a circle in terms of its circumference."
The area of a circle in terms of its radius is A = πr^2. To put this formula to use, we have to know the radius of the circle. The circumference of a circle in terms of its radius is C = 2πr, so a formula for the radius is r = C / (2π).
Now let's find a formula for the area of a circle in terms of its circumference:
C C^2
A = πr^2 = π { ---------------- }^2 = ------------
2π 4π
or:
A = (C^2) / 4π
Answer:
False
Step-by-step explanation:
Each f(x) increases by 8 therefore this equation is a linear function. If you where to graph it would be a straight line
Hope this helped :)
Answer:
Yes
Step-by-step explanation:
74/e < 12
Since e is in the denominator, e can not be 0.
If e > 0,
74/e < 12
74 < 12e
e > 74/12
e < 37/6
If e < 0,
(When you multiply by e, which is a negative value, inequality reverses)
74 > 12e
e < 74/12
e < 37/6
I'm going to assume you mean 3 to the power negative 5.
3^-5
Use rule [ x^-y = 1/x^y ]
3^-5 = 1/3^5 = 1/243
Best of Luck!
