Answer:
Looks correct to me.
Step-by-step explanation:
Volume of a cylinder = cross sectional area * height
so...
height = 3m
cross sectional area = pi × radius^2
radius = 1/2 diameter
radius = 1/2 × 6 = 3
3.14 × 3^2
= 3.14 × 9
= 28.26
therefore...
volume of cylinder = 28.26 × 3
= 84.78 m^3
Answer:
You would round down, but not to 3. You would round it down to 4.
Step-by-step explanation:
If a decimals last digits are five or more, you would round up. But 4.22 would be rounded down because its less than 5.
$4.27
You subtract 17-3 = 14
Then multiple 14 by 0.13
Then add it by 2.45
Giving you 4.27
