A cylinder has a diameter of 10 units. Its radius ___ is units. If its height is twice its radius, its height is____ units. Its volume is about ___cubic units
Answer:
Volume of cylinder is 785.7 square units.
Step-by-step explanation:
Given the diameter of cylinder 10 units. The height is twice its radius. we have to find its volume.
Diameter, d=10 units
⇒ \(\text{Radius,}r=\frac{d}{2}=\frac{10}{2}=5units\)
Also given height is twice its radius.
⇒ Height=2(r)=2(5)=10 units
\(\text{Volume of cylinder=}\pi r^2h=\frac{22}{7}\times 5^2\times 10=785.4 units^2\)
hence, volume of cylinder is 785.7 square units.
Answer:
Blank 1 - 5
Blank 2 - 10
Blank 3 - 785
Step-by-step explanation: The diameter is always 2 times the radius so divide 10 by 2 you get 5. Then, for the next part, it says that the height is twice the radius so multiply it by 2, 5 x 2 is 10. To find the volume you do
V = π r2 x h
the radius is 5.
V = π (5)2 x h
5 squared is 25
V = π (25) x h
25 x π or 3.14 is
78.5
so what you are left with is
V = 78.5 x h
The height is 10
V = 78.5 x 10
V = 785
Hopes this helps :D
