volume = π x r^2 x h
diameter = 20, radius = 20/2 = 10
10^2 = 100
100 * 5 = 500
volume = 500π cubic cm

Answer:
Thomas has 45
Emma 30+45=75 pound
Step-by-step explanation:
Ratio is 3/5
Tomas receives x money
Emma receives x+30
3/5=x/30+x
3(30+x)=5x
90+3x=5x
90=5x-3x
90=2x
x=90/2=45
Thomas has 45
Emma 30+45=75 pound
45/75=3/5
