Horse Fence

Farmer Finnegan needs to build a fence to keep his horses on his property. He only has a little over 1.5 miles of fence materials, but there’s also a mile-long straight river running through his property. What shape should he use for the fenced in area to give his horses the most space possible?

Our dear friend Finnegan should build a half-circle fence with the river as the diameter, giving the horses about 0.4 square miles to frolic and play in.

Area of semi-circle = πr2 / 2 = π × .5 miles2 / 2 = 0.3927

Made of ten but two we make,
When assembled others quake,
Five apart and we are weak,
Five together havoc wreak.

A One Letter Change

At my start I last a mere eleven days,
But change one letter and I’m over 31 years.

What am I?

One million seconds (about 11 1/2 days).

Change the “m” to a “b” to get one billion seconds (about 31.7 years).

It’s rather surprising that a million seconds and a billion seconds differ by such a large duration.
