Answer: 628
Step-by-step explanation:
2πr^2+2πrh
2(3.14)(5)^2+2(3.14)(5)(15)
2(3.14)(25)+2(3.14)(75)
2(78.5)+2(235.5)
157+471

Answer:
7/10
Step-by-step explanation:
red + green = 50 + 20 = 70 marbles
Total marbles = 50 + 30 + 20 = 100 marbles
P(red or green) = 70/100
P(red or green) = 7/10

Solve for t
t=12.77 =13 years
2010+13=2023
So the answer is c
