Answer:
C=89.2
Step-by-step explanation:
The formula of the circumference of a circle is C=2piR (or C=piD). Now, when calculating, plug in the numbers, giving you C=2pi14.2. Multiply everything, you get a super long irrational number; just round. You will get 89.2.
180
192-12=180
b = 50%
P(Heart or Club)
= P(Heart) + P(Club)
= 13/52 + 13/52
= .25 + .25
= .5 --> 50%
$638.4
19% of 1120 = 212.8
212.8 x 3 = 638.4
21.9
circumference = pi x diameter
3.14 x 7 = 21.9
