Determine the radius of a cone that has a volume of 230 ft' and a height of 15 ft. Round the answer to the nearest tenth.

the formula for finding cone volume is V=πr²× 1/3

Step-by-step explanation:

230=3.14×x²×1/3

we have to solve for X that is our radius

14.8

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
