To solve for the area of a circle, we need to know the formula for area first.
Formula: A = π r2 where r is the radius and π is 3.14.
Since 24 is the diameter, we can convert it into radius by using r= ½d;
r= ½d
r= ½*24
r= 12.
Substitute the value of r and π.
A = π r2
A = 3.14 (12²)
A = 3.14 (144)
A = 452.16 in² or 452.2 in² if rounded off to the nearest tenths.
