How do I find the diameter and circumference when given the area?
JulijaS [17]

Hello from MrBillDoesMath!

Answer:

Diameter = 2r = 2 (sqrt(24/Pi))

Circumference =  4 sqrt(6Pi)


Discussion:

Given:

     Area  of circle =  Pi r^2

               24 = Pi r^2        =>  (as Pi r^2 is the formula for area of a circle)

               24/Pi = r^2       =>  ( now take the square root of both sides)

               r= sqrt(24/Pi)


Diameter = 2r = 2 (sqrt(24/Pi))

Circumference = 2 PI r = 2Pi (sqrt(24/Pi))

                                       = 2Pi (sqrt(24)/sqrt(Pi) )

                                       = 2Pi (2sqrt(6)/sqrt(Pi) )

                                       =  4 (pi/ sqrt(Pi) ) sqrt(6)

                                       = 4 sqrt(Pi) sqrt(6)

                                       = 4 sqrt(6Pi)


Thank you,

MrB

Using the functions f(x) = (3 - x)/(x2 + 4) and g(x) = 3x, find the value of (f*g)(2).
wariber [46]

9514 1404 393

Answer:

  (f×g)(2) = 3/4

Step-by-step explanation:

For each of the functions, put 2 where x is and evaluate the expression.

  f(2) = (3 -2)/(2² +4) = 1/8

  g(2) = 3×2 = 6

Then the product is ...

  (f×g)(2) = f(2)×g(2) = (1/8)×6 = 6/8

  (f×g)(2) = 3/4
