Answer:
pick 1
Step-by-step explanation:
The diameter of the sphere is 60 mm which means its radius is 30mm. <span>The radius of a sphere is increasing at a rate of 5 mm/s.
The formula for the radius when the time is x second would be:
</span>r(t)<span>= 30+ 5x
dr/dt= 5
The speed of </span><span>volume increase </span><span>of the sphere volume would be derived from sphere volume:
</span>V(r)=4/3* pi * r^3<span>
dV/dt= 4/3 * pi * 3r^2 * (dr/dt) =4/3* pi * 3(30)^2 * 5 = 18000 pi= 56571 mm^3/s</span>

Step-by-step explanation:
Answer:
It can cover a distance of 100m.
Step-by-step explanation:
Given that:
Speed = v = 10m/s
Time = t = 10s
We know that:
Distance = Speed * Time
d = v*t
d = (10m/s)*(10s)
d = 100m
