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

What is the exact area of a circle whose diameter is 24 cm-example-1
