Answer:

50 cm

Step-by-step explanation:

Circumference = $2\pi r$

$2\pi r$ = 157

$\frac{2* 22 r}{7}$ = 157

r = 157 * 7 / 44

r = 24.97 cm

r can be rounded to 25cm

so the diameter = 50cm

The probability of wearing blue shirts on both days is 3/28.

<h3>What is probability?</h3>

Probability is the measure of the likelihood of an occurrence.

8 shirts are available out of which 3 are blue, 1 is green and 2 are white.

P(blue on Monday) = 3/8
