Pi times pi equals 9.869604401089358 (to 15 decimal places).
The square value 9.8696 is commonly used.
If you use (pi)2 = 10 in your calculations, your answer is only wrong by about 1.3% .
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
The formula for finding the area of a circle is pi times the radius squared. Let's find the radius of the circle. 100 pi/ pi= 100. Squarerooted, the radius is 10. The formula for finding the circumference of a circle is 2 times pi times the radius. So, plug in: 2 times pi times 10 equals 20 pi! Your final answer: 20 pi (or, if you use decimals, approximately 62.8)
(pi times radius squared) plus (pi times radius times slant).
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.
the same as pi squared, which is 9.86960440109
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
pi^2
area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)
Pi 46 is solved by taking pi and multiplying by 46. So pi times 46 = 144.513262.
The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.
4 times pi times 4 divided by 2 is 78.9568352087
The formula is 2 times radius times pi or the diameter times pi. Circumference is 2r times pi. Assuming you are referring to a circle.
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
When you multiply 12.8 times pi the exact answer is12.8 Pi, but you can round off the answer to40.192because pi is about equal to 3.14.
