Answer:
vol = 6.23 cm3
Step-by-step explanation:
dia = 1.26 cm

vol = area * L
vol = (pi * 1.26² / 4 ) * 5
vol = 6.23 cm3
Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number
