Question

Circumference 180 find its area

Answer 1

Answer:

Perimeter of △ABC= 180cm. So the side of an equilateral triangle is 60cm. Area of the equilateral triangle is given as Area = √34x2 where x is the side of the equilateral triangle. Hence the area of the triangle is 1558.84cm2.

Answer 2

Answer:

2577.27 cm^2

Step-by-step explanation:

Circumference of a circle = 2πr, where r is the radius.

Given, Circumference = 180.

So 2πr = 180,

r = 180/2π

r = 180 x 7/44

r =  315/11

Now Area of a circle = πr^2

= 22/7 x 315^2/11^2

= 2577.27 cm^2
