Answer :
Answer:
Circle A: 265.9 cm²
Circle B: 2002.96 inches²
Step-by-step explanation:
Hi there!
Circle A
[tex]A=\pi r^2[/tex] where r is the radius of the circle
Plug in the radius 9.2 cm
[tex]A=\pi (9.2)^2\\A=84.64\pi \\A=265.90[/tex]
Therefore, the area of the circle is 265.9 cm² when rounded to the nearest hundredth.
Circle B
[tex]A=\pi (\frac{d}{2}) ^2[/tex] where d is the diameter of the circle (because radius=diameter/2)
Plug in the diameter 50.5 inches
[tex]A=\pi (\frac{50.5}{2}) ^2\\A=\pi (25.25) ^2\\A=637.5625\pi \\A=2002.96[/tex]
Therefore, the area of the circle is 2002.96 inches² when rounded to the nearest hundredth.
I hope this helps!
