Answer:
62.8
Step-by-step explanation:
To find the area of metal required, we calculate the area of the outer circle and subtract the area of the two inner semicircles. The area of the outer circle is,
AOC=πr2=π(62)=113.0973 in2
The area of the inner semicircles is,
AIC=2⋅12πr2=π(42)=50.26548 in2
The total area of the sign is,
A=113.0973−50.26548=62.83182 in2
Rounded to one decimal place, the area of metal required is 62.8 square inches.
