Question 92

The circumference of a circle is equal to the perimeter of an equilateral Δ. If the radius of the circle is 14 cm what is the length of the side of the equilateral Δ?

Solution

Let the side of equilateral triangle = $$x$$ cm and radius = 14 cm

Perimeter of equilateral triangle = Circumference of circle

=> $$3 \times x = 2 \pi r$$

=> $$3x = 2 \times \frac{22}{7} \times 14$$

=> $$3x = 44 \times 2 = 88$$

=> $$x = \frac{88}{3}$$ cm

=> Ans - (B)
