Answer:

Area of the circle= 3.14units^2

Step-by-step explanation:

Circumference of the circle=6.28 units

Finding the radius:

Circumference of a circle =2*\pi *r

6.28=2*\pi *r\\

As, \pi =\frac{22}{7}=3.14

So,    

           6.28=2*3.14*r

          6.28=6.28*r

Dividing by '6.28' both side:

        r=6.28/6.28

           r=1unit

Area of the circle= \pi *r*r

                      =3.14*1*1\\\\=3.14*1\\\\=3.14units^2

Area of the circle= 3.14units^2

stiks02 [169]

Answer:

t >= \frac{25}{3} or 8.33333333333

Step-by-step explanation:

We need to set up an inequality where demand is less than or equal to 0. The inequality looks like this:

50 - 6t <= 0

50 <= 6t

t >= \frac{25}{3} or 8.33333333333
