Answer:
The circumference would be 62.83 rounded to 2 decimal places.
The area would be [tex]314.16cm^{2}[/tex].
Step-by-step explanation:
Circumference:
To find the circumference we need to do [tex]\pi[/tex] x d. Pi = 3.14 x diameter = 20cm equals to 62.83cm.
Area:
To find the area we need to half the diameter first as the radius is half the diameter. 20 divided by 2 = 10cm so that will be our radius. Then we need to do [tex]\pi x 10x^{2}[/tex] = [tex]314.16cm^{2}[/tex].
Hope that helps. x
