<span>v = 4/3*pi*r^3
derivating both sides with respect to t
dv/dt = 4*pi*r^2*dr/dt
when d = 1.7, r = 0.85, and dv/dt = 2:
2 = 4*pi*(0.85)^2*dr/dt
thus
dr/dt = 1/(2pi*(0.85)^2)
=1/(2*3.14*0.85^2)
=0.22</span><span />
R=1v+h([pi]h^2) all over 3
Answer:$1.25
Step-by-step explanation:
2 divided by 1.60=$1.25
3 divided by 2.40= $1.25
5 divided by 4.00= $1.25
8 divided by 6.40 = $1.25
Answer:
Just Transposition...
Step-by-step explanation:
12×7=84=d
92-49=43=e
28+57=85=f
96÷16=6=g
11×8=88=h
95+5-29=100-29=71=I
55-6+21=70=j
88+8÷4=96÷4=16=k
19+24-97=-97-43=54=m
-20+17+61=61+3=64=n
hope it helps
