Question 143957
Use ratios to find the diameter of the model.

{{{1/100 = x/10}}}
{{{0.1 = x}}}

The model diameter is .1

Area of a circle is {{{A = pi*r^2}}}
{{{d = 2r}}}
{{{r = d/2}}}

{{{A = pi*(d/2)^2 }}}
{{{A = pi* (.05)^2}}}
{{{A = 0.007853975 ft^2}

i square foot = 144 square inches
{{{A = 1.1309 square inches}}}
rounded to nearest tenth inch = 1.1square inches
