Question

A wire is bent to
form an equilateral
triangle. If the area
of the triangle is
43 cm2, what is
the area of the circle
formed (in cm?) by
the same wire?​

Answer 1

Step-by-step explanation:

s square is 43

s = 6.56 (approx)

perimeter of triangle is equal to perimeter of circle

6.56×3 perimeter of traingle

19.68 ~20

circference of Circle is equal to 20cm

2πr

2×3.14 r =20 cm

12.74cm

area of circle is = πr square

=3.14×12.74×12.74

=510cm square (approx)
