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

Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π)
coldgirl [10]
The area of a circle is equal to the radius squared times pie, basically:

{r}^{2} \times \pi

The radius is 3, so we multiply 3 times 3 times pie to get the area.

You're gonna want to plug in the following into a calculator:

3 \times 3 \times 3.14

After getting 28.26 from such calculator, you need to round to the tenths place. In this number, the tenths place is the 2 next to the decimal on the right. Because the number after the 2 is a 6, that means we need to simplify the answer to (28.3). When you are rounding a number, you look at the number to the right, if it is 5 or bigger, add one and remove the rest, if it is less than 5, just get rid of the rest and leave it as it is.
