Find the area of a circle with a radius of 2. Either enter an exact answer in terms of ar or use 3.14 for and enter your answer as a decimal.

Answer

12.5663706

Step-by-step explanation:

if r=2

the equation for area of circle is 2pier

plug in r and you get 2pi2

mulitply it is 12.5663706 or 4pi.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
