Rem4 x 3.14 ember the Circle Equations
C = 2 pi r
A = pi r^(2)
If 'r' (radius) = 2 units then
C = 2 pi x 2 = 4 x pi = 4 x 3.14 = 12.56 units.
A = pi 2^(2) = 3.14 x 4 = 12.56 units^(2)
NB pi = 3.141592.... It is an irrational constant. However, when learning circle equations you are usually given pi = 3.14 , or 3.1416 or 22/7, These are only approximations given for ease of learning.
The answer is 12.56
One example of a math question where the answer is 16 could be: "What is the result of 4 multiplied by 4?" In this case, 4 multiplied by 4 equals 16.
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).
If you use pi as 3.14, the answer is 12.56. If you use the pi button on your calculator, it is still simplified to 12.56, but if you want the full number, it is 12.56637061. The algebra is pi multiplied by diameter OR pi multiplied by radius squared Pi is often just used as 3.14
The area of a circle is 'pi' multiplied by the square of the circle's radius.The volume of a circle is zero.The volume of a sphere is (4/3 pi) multiplied by the cube of the sphere's radius.

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).
Maybe. It depends on the number that you are multiplying. Pi multiplied by (1 / 4pi) = 1/4. A quarter is definitely rational.
The diameter squared multiplied by Pi/4 Area = Pi/4 x D2

Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.
Pi=3.14 in basic math
A sphere is a geometrical globular shape which has a volume of 4/3*pi*radius3 and a surface area of 4*pi*radius2
