Sagot :

The area formula of a circle is π×[tex] r^{2} [/tex] 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×[tex] 12^{2} [/tex] do the exponents first.  12×12=144.  Now multiply that by pi. 144×3.14=452.16
