Answer:

The diameter would be 11 feet

Step-by-step explanation:

C = pi * d

we don't know D so we rearrange the equation to solve for D by dividing both sides by pi:

C/pi = d

Now we plug in everything

11pi/pi = d

The pi cancel each other out leaving with 11 feet

Therefore D = 11 feet

A bicycle store cost $2400 per month to operate. the store pays an average of $60 per bike. the average selling price of each bi

algol [13]

The store must sell 40 bikes each month to break even.

Step-by-step explanation:

Given,

Operating cost of store = $2400

Average paid per bike = $60

Average selling price of one bike = $120

Let,

x be the number of bicycle.

Therefore, to break even

Total operating costs per month = Total bikes sold each month

2400+60x = 120x

Subtracting 60x from both sides

$2400+60x-60x=120x-60x\\2400=60x\\60x=2400\\$

Dividing both sides by 60

$\frac{60x}{60}=\frac{2400}{60}\\x=40$

The store must sell 40 bikes each month to break even.
