Step-by-step explanation:
could not find the formula ?
the volume of a cylinder is ground area × height.
and the ground area is a circle.
so, all in all we get
pi×r²×h
with r being the radius (half of the diameter), and h being the height.
in our case we get
pi×(140/2)²×10 = pi×70²×10 = 49000×pi =
= 153,938.04... cm³
Answer:
113.17
Step-by-step explanation:
add them but line up the decimal. remember smallest number first. You know actually it don't matter
(3^2)^-2
9
9^-2 = 1/9^2 ---> 1/81
should be 1/81
