what is area of circle whose circumference is 88cm

Answer 1

here is ur answer....

Answer 2

$\huge\textbf{Heya}$

$\red{Answer 1.}$

Side = a = 12 cm (given)

Area of the equilateral triangle
= √3/4 × a²

= √3/4 × (12)²

= √3/4 × 12 × 12

= √3 × 12 × 3

= 36√3 cm²

$\red{Answer 2.}$

Circumference of circle = 88 cm

2πr = 88

2 × 22/7 × r = 88

44/7 × r = 88

r = 14 cm

Radius of circle = 14 cm

Area of the circle
= πr²

= 22/7 × 14 × 14

= 22 × 14 × 2

= 616 cm²

$\textbf{Hope this helps you.}$
