    Area of a circle is pi x r x r

    then you substitute the numbers in

    therefore you would get 3.14 x 11 x 11 = 379.994

    to the nearest hundredth degree would to 379 cm squared because you are finding the area so you put a small 2 above the cm

    the person above has done it wrong as they have halved the radius but you only have the diameter to get the radius and they have used the wrong equation
