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
Answer:
$28.50
Step-by-step explanation:
It declined $7.50 in 3 days then increased $4 in 2 days
<span>So lets see how does knowing that 5 divided by 8 = 0.625 helps us write the decimal for 4 5/8. First lets write 5 divided by 8 like a fraction: 5/8=0.625. Now we can see that 5/8 is in the number 4 5/8 so we can easily write it as: 4 + 0.625 = 4.625. So this is how it helps us. </span>
