Answer from: meccadm

Hello!

In this situation, we know that the circumference is 16π. The formula for circumference is C=Dπ. This tells us that our diameter equals 16 inches.

To find the area, we multiply the radius squared by pi (we will use 3.14.) The radius is half of the diameter, and as we know that it is 16, our radius would be eight. Eight squared is 64. If we multiply 64 by pi, we get 200.96 inches as our area.

I hope this helps!

The equation used to find the area of a circle is $\pi$ ×radius²=A

The equation used to find the circumference of a circle is $\pi$ ×diameter=circumfrence

1) You will need your diameter and radius in order to find the area of the circle. In this case, working backward will help.

2) Set your circumference equation equal to 16 $\pi$ and solve for diameter by dividing by $\pi$ on the left and right sides.

3) From this, you will find that your diameter equals 16in.

4) Half of a circles diameter is the radius so divide 16in (diameter) by 2 to find the radius. This will come out to be 8in.

5) Now that you know the radius, you can plug in the radius to the area of a circle equation to find the area of the circle: $\pi$ ×(8)²

6) $\pi$ ×(8)²= 201.06in²=A

Answer from: Quest

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
