Answer:
A I used 3.14 for pi which is why I'm a little out.
Step-by-step explanation:
The diagram makes it hard to tell. Where exactly is the arrow pointing?
I think it means the diameter.
r = d/2
r = 4
Volume = 4/3 * pi * r^3
Volume = 4/3 * 3.14 * 4^3
Volume = 4/3 * 3.14 * 64
volume = 4 * 64 * pi / 3
Volume = 256 pi/3 = 267.9
Answer:
ok
Step-by-step explanation:
120
You can find out how many she has graded by multiplying 150 by the decimal version of 20% (.20). Then, subtract the number you get by 150.
=-35(4s-t)+21(4s-t)
=-140s+35t+84s-21t
=-140s+84s+35t-21t
=-56s+14t
