Question

∆ABC is an equilateral triangle with side 6 cm. A circle is drawn on segment BC as diameter. Find the length of the arc of this circle intercepted within ∆ABC​

Answer 1

Answer:

lenght of the arc will be 9.42 cm.

Step-by-step explanation:

now here we got triangle ABC as an equivalent triangle,

and line segment BC=6 cm. ( Given )

radius of circle will be 3 cm ( by calculation )

now perimeter of circle which is 2/ pie * r^2

we got perimeter = 18.84 cm

now to find measure of one arc,

• total measure/ 2

= 18.84/2

= 9.42 cm

we got measure of one arc = 9.42 cm
