Amodel car has tires that are 2 inches in diameter. how far will the model travel in 20 revolutions?

Answer

Find out the  how far will the model travel in 20 revolutions .

To proof

Formula

where r = radius

As given in the question

A model car has tires that are 2 inches in diameter.          

Radius = 1 inches

than

the circumference of the circle = 2 × 3.14

                                                    = 6.28 inches

the model travel in 20 revolutions = 20× 6.28

                                                         = 125.6 inches

125.6 inches will the model travel in 20 revolutions

Hence proved

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!
