Answer:
6.25cm
Step-by-step explanation:
V/π x r2 = h
π * 64 = 201.06192983
1256.63706144/ 201.06192983 = 6.25cm
1256.63706144/ π = 400 then to check.
If you are given area cylinder this may help you as it takes 3 minutes to learn off by heart.
Cylinder Area A= 2*π * r*h + 2*π * r^2 = 4 value
2*π = 6.28318530718
6. = six 1 value
-Twentyeightythreeone 4 value
Eightfivethreezero 4 value
SevenEighteen 3 value
Quickly write down those values and remember them
Multiply it by the square radius 8^2 + then press store on calculator. We use 2*π the second time just add the radius, take this product and add it to the last. Then store bring the Area up and divide with the last stored entry.
- we get the height.
To find h we A / 2πr2 + 2π * r) = h
The height of this cylinder is 6.3cm
The formula for calculating the volume of a cylinder is expressed as:
[tex]V = \pi r^2h[/tex]
where
r is the radius = 8cm
h is the height
Substitute the given parameters to have:
400π = π(8)²h
400 = 64h
h = 400/64
h = 6.3cm
Hence the height of this cylinder is 6.3cm
