Question

Find the circumference and area of each circle. Include the formula thank you

Answer 1

Circumference=16 pi
Area=64 pi
Below is my methods

Answer 2

Answer:

Circumference: 50.27 cm

Area: 201.06 cm²

Step-by-step explanation:

Hi there!

1) Determine the circumference

$C=\pi d$ where d is the diameter of the circle

Plug in the diameter (16 cm)

$C=16\pi\\C=50.27$

Therefore, the circumference is 50.27 cm when rounded to the nearest hundredth.

2) Determine the area

$A=\pi r^2$ where r is the radius

Plug in the radius (16/2=8)

$A=\pi (8)^2\\A=64\pi\\A=201.06$

Therefore, the area of the circle is 201.06 cm² when rounded to the nearest hundredth.

I hope this helps!
