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

Circumference: 50.27 cm

Area: 201.06 cm²

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!
