Question

the area of a circular tin plate is 38.5m² find its circumference

Answer 1

$01 {85 {70 {60.3 \times .6 \times < . \times .. - - = 6116483 \sqrt[0 { {1 { { { { { { { { { { { { {2151524222...}^{?} \times \frac{?}{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} }^{?} \times \frac{?}{?} ]{?} }^{?} }^{?} }^{?} \times \frac{25522}{?}$

Answer 2

Given,
Area = 38.5m²

We know,
Area of circle = πr²
38.5 * 7/22 = r²
12.25 = r

We know
Circumference = 2πr
                        = 2*22/7*12.25
                        = 77 m
