Respuesta :

Well this is pretty simple

for the area we need to use the formula A=3.14*radius*radius

so we just plug it in and we get 3.14*8*8 which is 200.96 centimeters squared

for circumference we need to do C=3.14*diameter

to find the diamter we need to do 8 (radius) x 2 which is 16

plugging it in that would be 3.14 * 16 which is 50.24

So in this case the the area is 200.96 and the circumference is 50.24 :)
