Question

if the circumference of a circle is 70 cm , find its radius

Answer 1

HEYA MATE, HERE IS UR ANSWER

$<b><i>Circumference = 2 pie r -----(1)$

But according to the question


Circumference of the circle =70 cm ----(1)

Equating (1) and (2)

2 pie r=70

2×$\frac{22}{7}$× r=70

$\frac{44}{7}$×r=70

r=70×$\frac{7}{44}$

r=11.135 (approx )

r=11.14 cm (approx)
