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.
Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.
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
4 * 3.141592653589793 = 12.56637
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

The formula for the volume of a sphere is based on the radius of the sphere. It is equal to 4/3 multiplied by pi, multiplied by the radius cubed.
The volume V is the area of the circle multiplied by the height The area of the circle is A=pi*radius2 = pi*(28/2)2 V = pi*(28/2)2*4 = 2467.76 with pi=3.14
1/3 multiplied by pi multiplied by radius squared multiplied by height
