Question

1) If the circumference of a circle is 176cm. Find it's radius. * 1 point a) 28 cm b) 14 cm c) 42 cm d) 21 cm​

Answer 1

Answer:

Circumference =176 cm

So radius=

$2\pi r \\ \\ = 2 \times \frac{22}{7} \times r = 176 \\ \\ = 28 \: cm \\ \\ = \frac{176}{1} = \frac{44}{7}r \\ \\ = \frac{1232}{44} \\ \\ simplify$

$\boxed{radius = 28 \: cm}$
