The area formula of a circle is π×\(r^{2}\) pi is 3.14 and r is the radius. The question gives you the diameter. To find the radius with a given diameter, divide the diameter by 2. 24÷2=12. The radius is 12. Now we can multiply 3.14×\(12^{2}\) do the exponents first. 12×12=144. Now multiply that by pi. 144×3.14=452.16
