Volume of the first dwarf planet (r₁ = 832 mi):
Volume of the second dwarf planet (r₂ = 829 mi):
So difference between the volumes is:
or if we want exact value (we use (a³-b³) = (a-b)(a²+ab+b²) ):
Answer:
2km
Step-by-step explanation:
Distance = Speed ÷ Time
Distance = 3 ÷ 1.5 (as 1 hour and 30 minutes is an hour and a half)
Distance = 2km
So using the formula for the volume of a cone:
r^2pi x h/3
The height is always 4 times the radius, so:
h=4r
Now putting the values into the original formula:
r^2pi x 4r/3
Now to see how much the radius increases per second:
r^2pi x 4r/3=300pi
r^2 x 4r/3=300
r^2 x 4r=900
r^2 x r=225
r^3=225
The radius increases by the cubic square root of 225 cm per second.
f(s)= 225^1/3 cm
The answer is currently A so yep thats the answer ok
Yes because none of the x’s are the same
