Question

The radius of a circular rug is 4 feet. How much ribbing will you need to buy to go around the rug? Use 3.14 for ?. A) 13 feet B) 26 feet C) 51 feet D) 102 feet D) 628 feet

Answer 1

C =25.12 ft

I would get 26 ft

B) 26 feet

Explanation:

To go around the rug, we are looking for circumference

C = pi*d = 2*pi*r

C = 2*pi*4

C = 8pi

We are approximating pi by 3.14

C = 8*3.14

C =25.12 ft
