Circle in a triangle maths problem
WebAn equilateral triangle has all three sides equal and and all three angles equal to 60° The relationship between the side \( a \) of the equilateral triangle and its area A, height h, radius R of the circumscribed and radius r of the inscribed circle are give by: WebThe radius of bangle is 1.166 cm. Example 4: A girl wants to make a square-shaped figure from a circular wire of radius 49 cm. Determine the sides of a square. Solution: Let the radius of the circle be ’r’. Length of the wire=circumference of the circle= 2πr. = 2 × 22 7 × 49 = 2 × 22 × 7 = 308 c m.
