Find the circumference and the area of a circle with a diameter 9m.

Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.

Answer 1

circumference= 28.26

Area= 63.585

Step-by-step explanation: So, to do this question you have to know the formula for both circumference and the area. So to find the circumference you have to do

2*3.14*4.5 -(9/2)

= 28.26

And to find the area you have to do.

3.14*4.5^2

= 63.585

Therefore, those are the answers. Please let me know if they are wrong.
