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).
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 circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
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)
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
pi^2
area: (pi) times radius2 circumference: (pi) times diameter OR 2 times (pi) times radius :)
4 times pi times 4 divided by 2 is 78.9568352087
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.
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
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.
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.
