Explanation:
Area of full circle=Πr²
Area of half circle= Πr²/2
Diameter of circle= 6
Radius=r= 3
Area of half circle= Π(3)²/2
= (3.14*9)/2
= 28.26/2
= 14.13
Answer:
14.13
Explanation:
A=1/2[tex]\pi[/tex][tex]r^{2}[/tex]
substitute [tex]\pi[/tex] for 3.14 and r with 3 because half of diameter is 3.
A=1/2*3.14*[tex]3^{2}[/tex] 3 times 3=9
A=1/2*3.14*9
9 times 3.14 is 28.26
A=1/2*28.26
A=14.13
