Question

Solve for A if pi-symbol=3.14 and r=3 A=PIrSquared so what is the answer?

Answer 1

The solution for Area, A is 28.26 square units, if pi-symbol=3.14 and radius r = 3, A=PIrSquared.

Step-by-step explanation:

The given is,

                pi - $\pi$ = 3.14

                       r = 3

                      A = PIrSquared...................................(1)

Step:1

               Formula for area of circle is,

                         $Area, a = \pi r^{2}$......................................(2)

               Equation (1) and Equation (2) both are same, it is used to calculate area of circle.

               From given,

                        radius, r = 3

               Substitute the value of radius in equation,

                                     = $\pi (3^{2})$

                                     = $\pi$ × 9

                                     = 3.14 × 9                  (∵ $\pi$ =3.14)

                                     = 28.26

                        Area, a = 28.26 square units

Result:

      The solution for Area, A is 28.26 square units, if pi-symbol=3.14 and radius r = 3, A=PIrSquared.
