Answer:
Step-by-step explanation:
for the cylinder
27π = πr²h = πr²(2r) = 2πr³
for the sphere
V = (4/3)πr² = (2/3)(2πr³) = (2/3)27π
Answer:
243
Step-by-step explanation:
STEP 1: Evaluate the variables
9(2 + (5)(5))
STEP 2: Then from there you can multiply the equation
18 + 225 = 243
2 weeks = 14 day
14 * 15 = 210 seconds
210/60=3 hours and 30 minutes or 3.5 hours.
