The height of a cylinder is 4 yards. the volume of the cylinder is 452.16 cubic yards. what is the radius of the cylinder?

r = 5.9984789350480924657633167413961‬ yards

Step-by-step explanation:

h = 4 yards

V = 452.16 yards Cubed (cubic yards)

V = πh

452.16 = π*4

divide by pi and 4 and you get approx 35.98

35.981 =

the square root of 35.98 is approx 5.9984789350480924657633167413961‬

which is equal to r, or the radius

r = 5.9984789350480924657633167413961‬ yards

what is the answer to this

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

(a + b) (a^2 - a b + b^2)
