Answer: 1 1/8
Step-by-step explanation:
8/9
=9/8
=1 1/8
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
Hey there,
15 : 6
It can be simplified by dividing both numbers by 3
15 : 6
5 : 2
Hope this helps :))
