(1/2) π r² h = (1/2) * (3.14) * (30)² * 100 = ?
(30)² * 100 = 30 * 30 * 100 = 90,000.
So, we have: (1/2) * (3.14) * (90,000) ;
→ (1/2) * (90,000) = 45,000 ;
So, we have: (3.14) * (45,000) = 141,300 units.

Answer:
the answer is B
Step-by-step explanation: Its B because the vertex is in the middle
We are given the electricity cost as 5 cents per
kilowatt-hour. We should notice that the cost is actually in the form of:
electrical cost = cost / (power * time)
Therefore to get a number which is in terms of cents
alone (cost alone), therefore we should multiply the given electrical cost
value with the power and time.
Power = 80 watt = 0.08 kilowatt
Time = 24 hours
Therefore the cost is calculated as:
cost = electrical cost * power * time
cost = [5 cents / (kilowatt hour)] (0.08 kilowatt) (24
hour)
cost = 9.6 cents

3x+22.5 = 69.75
-22.5 -22.5
3x = 47.25
/3 /3
x = 15.75
