The correct answer to 38 is B
Answer: 7065 cm
Step-by-step explanation:
Find the volume as the bowl was a whole sphere and then divide the volume found by two, to get the volume of half the sphere.
(4/3) * π*(r^3) ≈ 14130 cm
14130/2 ≈ 7065 cm
This is an approximated result using π = 3.14
No, it's simplest form would be 2/5.
It took them 4 days until they arrived at their destination.
314 × 4 = 1256
Another way of solving it:
Total amount of miles ÷ miles per day = The amount of days.
1256 ÷ 314 = 4
