A= pie r squared
V=4/3 pie rcubed

1 Answer

  • Answer:

    [tex]\large\boxed{C=2\pi r}[/tex]

    Step-by-step explanation:

    A linear equation is an equation in which a variable is in the first power.

    The formula of a Circumference of a circle

    [tex]C=2\pi r\\\\2,\ \pi-\text{numbers}\\r-\text{variable}\\\\\boxed{\bold{YES}}[/tex]

    The formula of an Area of a circle

    [tex]A=\pi r^2\\\\\pi-\text{number}\\r^2-\text{variable in the second power}\\\\\boxed{\bold{NO}}[/tex]

    The formula of a volume of a sphere

    [tex]V=\dfrac{4}{3}\pi r^3\\\\\dfrac{4}{3},\ \pi-\text{numbers}\\r^3-\text{variable in the third power}\\\\\boxed{\bold{NO}}[/tex]
