Answer:
Circumference: 50.27 cm
Area: 201.06 cm²
Step-by-step explanation:
Hi there!
1) Determine the circumference
[tex]C=\pi d[/tex] where d is the diameter of the circle
Plug in the diameter (16 cm)
[tex]C=16\pi\\C=50.27[/tex]
Therefore, the circumference is 50.27 cm when rounded to the nearest hundredth.
2) Determine the area
[tex]A=\pi r^2[/tex] where r is the radius
Plug in the radius (16/2=8)
[tex]A=\pi (8)^2\\A=64\pi\\A=201.06[/tex]
Therefore, the area of the circle is 201.06 cm² when rounded to the nearest hundredth.
I hope this helps!
