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
12.56
Step-by-step explanation:
A = π x r^2
r =2
2^2 = 4
π × 4 = 12.56
First you subtract 9x from y and you get 45 - 9x = -y and you don't want negatives so you switch all the signs to get y = -45 + 9x
Answer:
2.5 hours.
Step-by-step explanation:
This is the answer because you will need to add both of their times together then divide it by 2. You divide it by two because there are 2 people.
