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
I'm sorry the picture is blurry. Could you post another one.
Answer:
y-2 = -5x
5x+y = 2 is the required equation of a line.
Answer:
Step-by-step explanation:
Given
x times by 9
Required
Write out an algebraic expression for the above.
Follow the instructions below to get the algebraic expression of the above.
1. First, write out the variable: x
2. Then write out an expression for "times by 9". This means multiply x by 9.
So, this gives x * 9.
x * 9 = 9x.
Hence, the expression for the above question is 9x
