The volume of a cylinder is 400π cm3 and the radius of its circular base is 8 cm. What is the height of this cylinder?

ENTER ONLY THE NUMERIC VALUE FOR YOUR ANSWER.

Round your answer to the nearest tenth if necessary.

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

2nd one in the first row is correct
