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

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 - = 3.14

                       r = 3

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

Step:1

               Formula for area of circle is,

                         ......................................(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,

                                     =

                                     = × 9

                                     = 3.14 × 9                  (∵ =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.

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
