Let D be the Diameter and C be the circumference.
C=D X À (pi, about 3.14)
C=1cm X 3.14
C=3.14cm
The circumference of the home button on an iPhone is 3.14cm.

how do this task ok hold the power button and the home button at the same time for 15 seconds then when your time is up dont let go of the home button wich is the circle button with the square in it then logg on YOUR itunes account and keep on holding the home button until it saya its down loading
the circumference of the circle divided by pi (button or 3.14) - Maths
First try resetting your iPhone by pressing both the menu button and the top button together for 30 seconds. When it asks you if you want to slide to turn it off, ignore this message and KEEP holding!! Eventually, the screen will go off and your iPhone will be re-setting. Wait for a couple of minutes and turn it on the usual way. If it still asks you for the pass-code, the only way to get back into the iPhone is to plug it into the original computer with the original iTunes and press 'restore'.
Now that I've been able to find out the full question you were wanting answered for you, I've done the hard work of extracting the maths for it and re-writing the question. Now all that is needed is to rearrange the formulae for circumference and area of a circle to get a formula which will give the area from the circumference: Circumference = 2 × π × radius → radius = circumference ÷ 2π Area = π × radius² = π × (circumference ÷ 2π)² = π × circumference² ÷ 4π² = circumference² ÷ 4π I'll let you insert the relevant numbers and find the required area. ------------------------------------------------------------------------------------ Hint: circumference = 37.68 ft 4π means 4 × π π is the ratio of circumference to diameter of a circle and is approx 3.142, though your calculator will more than likely have a [π] button to supply the value to about 10 decimal places; you may need to put brackets around the divisor 4π.
Circumference = 2pi*r Circumference = 86pi
