pi was found when they realized that the radius of any circle is the amount of the perimeter multiplied by pi aka 3.14 and so on.
The diameter multiplied by (pi)2 . That's about 9.87 times the diameter.
Formula for finding the circumference of a circle: 2 multiplied by pi multiplied by radius
pi multiplied by the radius squared
Do you mean volume or surface area? volume = 4/3 x pi x r^3 (four divided by three, multiplied by pi, multiplied by radius cubed). surface area = 4 x pi x r^2 (four multiplied by pi, multiplied by radius squared).
Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.
1/3 multiplied by pi multiplied by radius squared multiplied by height
The answer is 12.56
449184.53
24.492, unless you want more digits of pi besides the standard 3.14. The circumference of a circle is equal to the diameter multiplied by pi, or the radius multiplied by two, then multiplied by pi. c = d*pi c = 2*r*pi c = circumference d = diameter r = radius pi = 3.141593
pi multiplied by r squared multiplied by height
60 cm x pi = 188,5 cm
When you multiply 5π by 50, you would get 250π. This is because 5 multiplied by 50 equals 250, and π is a constant approximately equal to 3.14159. So, 5π x 50 = 250π.
