Hello there,
Okay well first we right down what we already know:
- volume of 2,355 cubic inches
- the height is 10 inches
Now we write down the equation for the volume of a cone: V = πr²
- lets plug in what we know into the equation
2,355 = πr²
- now we simplify to solve for r
2,355 / 10/3 = 706.5 = πr²
706.5/π = r²= 224.89
- now since its r² we take the square root of 224.89
r = 15 inches
- for diameter we multiply 15 by 2
diameter = 30 inches
Hope I helped,
Amna

For this case we have an inverse variation equation given by two variables, x and y respectively. This equation is represented by: , we must find the value of the variation constant "k" when
and
. Then, we must substitute the values of "x" and "y" given in the inverse variation equation and find the constant "k":
Thus, the value of the constant of variation "k" is 10.
