The circumference of a circle is 11/pi. What is the area, in square inches, of the circle? Express your answer in terms of /pi.
eimsori [14]
So since 11/pi doesn't means 11 divided by pi but it means 11 pi

circumference=2pir
if circumerence=11pi
2pir=11pi
solve for r (radius)
divide both sides by pi
2r=11
divide by 2
r=5.5

area=pir^2
area=pi5.5^2
area=pi30.25

answer is area=30.25pi in^2

Jayden works for Float like a butterfly sting like a bee boxing club and received 660 on his last paycheck. If he gets paid time
alexandr402 [8]

Answer:

He make an hour if he worked 50 hours= 275

Step-by-step explanation:

Jayden worked for Float like a butterfly sting like a bee boxing club and received 660 on his last paycheck. Suppose he gets paid time and a half for overtime. How much does he make an hour if he worked 50 hours?

Sol:  Jayden received on his last paycheck = 660

Half for over time = 660/2 = 330

Paid time = 660 - 330 = 330

In 50 hours he makes = 330 x 50 = 16500

In one hour he makes = 16500/60         ( 1 hour = 60 min)

                                        = 275

A rectangular room is 3 3 times as long as it is wide, and its perimeter is 64 64 meters. find the dimension of the room.
lora16 [44]
Perimeter = 2L + 2W    (where L = length and W = width)

And we are given that L = 3W

So substituting for L, we have the equation:-

2(3W) + 2W = 64

6W + 2W = 64

8W = 64 

W = 8  meters

So the length = 3*8  = 24 meters

Answer:- Length = 24 m and Width = 8 m.
