A cylinder has a volume 45pi and radius 3. What is it’s height?
2 answers:
Answer:
the answer is 15
Step-by-step explanation:
Given data:
Volume V = 45 π and radius
r = 3 units The formula for the volume of the cylinder is V = B · H
Base of the cylinder is:
B = r² π = 3² π = 9 πFrom the formula V = B · H we get H:H = V / B = 45 π / 9 π = 5 units
H = 5 units
Answer:
The height is 5
Step-by-step explanation:
Given data:
Volume V = 45 π and radius r = 3 units
The formula for the volume of the cylinder is V = B · H
Base of the cylinder is:
B = r² π = 3² π = 9 π
From the formula V = B · H we get H:
H = V / B = 45 π / 9 π = 5 units
H = 5 units
