volume = PI x r^2 x h
volume = 20,000
radius = 20 ft
20,000 = PI x 20^2 x h
20,000 = 3.14 x 400 x h
20,000 = 1256 x h
h = 20,000 / 1256 = 15.9235 feet
round answer as needed
I took a picture of the work instead ^^
Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
= = ( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13
Answer:
it's 5
Step-by-step explanation:
you should use pythagoras theorem
Answer:
No
Step-by-step explanation:
-8 is less than -4. Negative numbers reverse the logic of positive ones: since positive 8 is more than positive 4, negative 8 is less than negative 4.
