Dude plz help A circle has an area of 25pi Another circle has a diameter 5 times the first. What is the diameter of 2nd circle

the Diameter of second circle is 50

Step-by-step explanation:

Area of first circle = 25 π

Diameter of first circle = d

Diameter of second circle= 5(Diameter of first circle) (because Another circle has a diameter 5 times the first)

We need to find diameter of 2nd circle.

First we find diameter of first circle.

The formula for area of circle is:

We also know that:

First we will find radius and using diameter formula we can find diameter of the circle.

So, radius of first circle is r = 5

Now, finding diameter of first circle:

So, Diameter of first circle = 10

Now, we know that diameter of second circle is 5 times the first

So, Diameter of second circle = 5(Diameter of first circle)

Diameter of second circle = 5(10)

Diameter of second circle = 50

So, the Diameter of second circle is 50

the answer is 99.

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!
