Answer:
B) 75π cm³
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (1/3)πr²h
Your cone has r = 5 cm and h = 9 cm. Putting these values into the formula gives ...
V = (1/3)π(5 cm)²(9 cm) = 75π cm³

Answer:
Inequality symbol = ≥
Solution = d≥4
Step-by-step explanation:
If a family drives 350 miles per day, then;
1 day = 350 miles
To determine the number of days they will use to reach at least 1400mles
d days = 1400miles
Divide both expressions
1/d = 350/1400
Cross multiply
350 * d = 1400
350d = 1400
Since we are told that it ia at least 1400miles, this means the total miles can be greater than 1400. Hence the correct inequality sign to use will be a greater than or equal to sign(≥).
The expression above becomes 350d ≥ 1400
Divide both sides by 3350
350d ≥ 1400/350
d≥ 4
Hence the solution that represent the situation is d≥ 4
