ivanzaharov [21]

easy peasy here we go..

so first circumference = 2π R

now it is given that circumference - 30 cm = Diameter;

Diameter = 2πR - 30 = 2 R { diameter = 2 times Radius}

now solving equations:

2πR -2R = 30

πR - R = 15

R ( π - 1 ) = 15

R ( 22/7 - 1) = 15

R ( 15/7 ) = 15

R = 15 x 7 / 15

R = 7 cm

Step-by-step explanation:

Worth raises to $100,000 by winning both races

Worth raises to $50,000 by winning one race

Worth decreases to $10,000 by loosing both

Probabilty of winning both races= $0.2\times 0.3$

Probabilty of winning one race= $0.2\times 0.7+0.8\times 0.3$ =0.38

Probabilty of loosing both races= $0.8\times 0.7$ =0.56

Expected profit= $0.06\left ( 100,000-20,000\right )+0.38\left ( 50,000-20,000\right )+0.56\left ( 10,000-20,000\right )$

=$10,600

both angles have to add up to 180º because they are co-exterior angles on parallel lines.

$2(x+5)+102=180\\2(x+5)=78\\2x+10=78\\2x=68\\x=34$
