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>
Answer:
13
Step-by-step explanation:
6-(-7)=13
Answer:
See below.
Step-by-step explanation:
There are three sheets of 10 stickers. This is equal to 30 stickers. There are also 30 single stickers. Split the single stickers and give Gary and Jill 13 each. Then Gary and Jill can each take a sheet of 10. They will both have 23 stickers.
Answer:
A
Step-by-step explanation:
The answer is (-2, 10) because when reflecting over the x, change the sign of y. When reflecting over the y, change the sign of x.
