Question

What is the diameter of a circle if the area of the circle us 10201 88 (assume that the value of 3.19) ?​

Answer 1

Answer:

Diameter of circle is 1131.04 unit

Step-by-step explanation:

Given:

Area of circle=1020188 sq.unit

As we know that area of circle =$\pi$ × $r^{2}$     (where r =radius of the circle)

                                 1020188 = 3.19 × $r^{2}$     (given $\pi$ =3.19)

                                 ∴$r^{2}$ = 1020188 / 3.19

                                       =319808.15

                                 ∴ r =$\sqrt{319808.15}$

                                      =565.52 unit

Radius of circle=565.52 unit

Diameter of circle = 2× radius

                              = 2 × 565.52

                            =1131.04 unit
