Question

I need help with math. Please show your work haha.

Answer 1

Everything is squared.

9) 2π(6) = 37.699cm

10) 2π(9) = 56.548yd

11) 2π(9) = 56.548in

12) 2π(7) = 43.982m

13) 2π(11) = 69.115m

14) 2π(2) = 12.566ft

Explanation:

To find the circumference it's 2πr.

To find the radius, cut the diamter in half.

9) 2π(6) = 37.699cm

10) 2π(9) = 56.548yd

11) 2π(9) = 56.548in

12) 2π(7) = 43.982m

13) 2π(11) = 69.115m

14) 2π(2) = 12.566ft

Answer 2

For all of these, I used 3.14 for pi
To find the circumference, multiply 2*pi*radius
Remember for the ones that show diameter, divide it by 2 to get the radius.
I hope this helps!!
