Answer:

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
