Answer:
8.565
Step-by-step explanation:
Volume=4/3pir^3
3000m^3=4/3pir^3
3000/4/3=pir^3
25/pi=r^3
approx 78.539=r^3
r=4.2825
we know,
2r=d
d=2×4.2825
d=8.565
You can round the answer off yourself :3
Answer:
50 black keys
Step-by-step explanation:
for every set of 7 white keys there are 5 black keys
72/7 = 10
so there is a total of 10 full sets of keys
then you have 2 white keys remaining but that doesn't matter because they will just be on the dies and already have a black key next
so this means that you only have to calculate the number of 10 sets of black keys and thats 5 x 10.
hope this helps : )
