we know that
3/4 inches represents 3 inches of actual clock ----> given
so
Applying proportion
Find out how much represents 11 inches in the actual
3/0.75=x/11
solve for x
x=(3/0.75)*11
x=44 in
that means
The diameter of the actual clock is 44 inches
so
the radius of the actual clock is
r=44/2=22 in
Find out the area
