Answer:

Step-by-step explanation:

3in/4 = 0.75in(Diameter) for each circle

r = 0.375

A = πr^2

A(for 1 circle) = 0.141π

A(for 1/4 circle) = 0.035π

A x 4 because we have 4 circles =

0.141π

0.141π(area of middle) + 0.141π(area of circle) =

0.282π or 0.886in^2

If a metal sheet is 1.2mm thick how must be put together to have thickness of 1.44 cm

dedylja [7]

First convert 1.2mm to cm

10mm = 1cm

so 1.2mm = 0.12cm

Then divide 1.44cm by 0.12cm
that equals to 12.

so you need 12 sheets to make it 1.44cm

You are researching the price of MP3 players. You found an average price of $58.80. One MP3 player costs $56 and another costs $

Butoxors [25]

The price of third MP3 player is $58.40

Step-by-step explanation:

Given,

Cost of one MP3 palyer = $56

Cost of another MP3 player = $62

Average price of MP3 player = $58.80

Let,

Cost of third MP3 player = x

Average = $\frac{Sum\ of\ costs}{Number\ of\ items}$

${58.80}=\frac{56+62+x}{3}$

Multiplying both sides by 3

$3*{58.80}=\frac{56+62+x}{3}*3\\176.40=118+x\\176.40-118=x\\58.40=x\\x=58.40$

The price of third MP3 player is $58.40
