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
