I think the answer is 169.65ft.
To solve for the time an object takes to hit the ground, the equation
<em>y</em> <em>= y₀ + v₀t + ½gt²</em>, or just <em>0 = y₀ +½gt²</em> since there is no initial velocity and the final y position is 0 (since it is on the ground). Therefore, <em>t = (−2y₀/g)^½.</em>
(-2*60/-9.8)^½ = 3.50 seconds.

<span>x+<span>(x+2)</span>+<span>(x+4)</span>=48</span>
3x+6=48
Minus 6 to both sides
<span>3x=42</span>
Divide 3 to both sides
<span>x=14</span>
Get the next two integers
<span>x,x+2,x+4 or 14,16,<span>18 = 48 is you Answer</span></span>
X^2 + y^2 = 225
The radius is 15.
