V = 30 ft^3

B = 8 ft^2

Answer 1

the answer is 30=1/3(8h)

Explanation:

i had it in a test an i got it right

Answer 2

Answer: The height of the cone is

`h = (45)/(4)`

Explanation:

Step 1:-

using formula Volume of the cone given base and height of the cone is
`V=(1)/(3)  (base)(height)`

Given Volume of the cone is V = 30 ft^3

Given base of the cone is B = 8 ft^2

Step 2:-

`V=(1)/(3)  (base)(height)`

substituting values, we get

`30 = (1)/(3) ( 8) ( h)`

cross multiplication, we get

`(30 X 3 )/(8)`

simplification we get

`h = (45)/(4)`

Final answer :- The height of the cone is

`h = (45)/(4)`
