4√400 / 4√ 5 ( both are 'fourth roots ')
= 4√ (400/5)
= 4√80
= 2.99 to nearest hundredth
Answer:
use the formula r = square root of (V / (pi x h))
david's procedure is correct becsuse Keisha didnt put the correct value of sin theta in equation, she forgot to mention negative sign. though solution are same but in other case it could have gone wrong
Answer:
the volume of a cylinder = V=Ah =pirsqh
=pie × r sq × h
= 3.14×4 ×4×9 = 452.16 so thats eliminated?
Volume of a cone = V= 1÷3pirsqh
= 1/3×3.14×4×4×9 = 150.72
volume of cylinder = 2×pi×r×h+2×pi× r×r
=241.645
not sure choose the ones you think a closest?
T-2(3-2t)=2t+9
t-6+4t=2t+9
5t-6=2t+9
5t-2t=9+6
3t=15
t=15/3
t=5
