Question

ABEDC is a pentagon such that
ABC is an equilateral triangle and
BEDC is a square of side 2 cm. A
circle passes through its vertices A,
E and D. What is the circumference
(in cm) of the circle ?​

Answer 1

Answer:

2√2π

Step-by-step explanation:

first draw a pentagon and inscribe equilateral triangle and square and plot the points A,B,E,D,C, now we have to find the circumference of the circle ,

first he has give each side of the square is 2

and the diagonal of the square is 2√2

then the radius of the circle is √2

so the circumference of the circle=2πr=2√2π
