Step-by-step explanation:
step 1. the area of a circle is A. A = (pi)r^2.
step 2. if the diameter is 8 cm then the radius is 4 cm.
step 3. A = (pi)4^2
step 4. A = 16(pi) = 50.24 cm.
Answer:
Step-by-step explanation:
A=[tex]\pi[/tex][tex]r^{2}[/tex] Diamter is half the radius so the radius is 4
A= 3.14 times [tex]4^{2}[/tex] [tex]4^{2}[/tex]= 16
A= 3.14 times 16
A=50.24
rounded answer will be 50.2
