hope I can help man. good luck.
Answer: it’s c.3
Hopes this helps. Um... can I please have brainliest
Step-by-step explanation:
According to the question requirements
v= 4/3*pi*r^3
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/dtthus the the speed of increasing of the balloon's diameter is
dr/dt = 1/(2pi*(0.85)^2)
=<span>0.2203 ft/min</span>
