Question

Find the radius of a circle whose circumference is 140
​

Answer 1

Answer: Your diameter would be 44.56338407 and your Radius would be 22.28169203.

Explanation:

All you have to do is take your circumference and divide that by pi, then you get your diameter. Since your diameter is doubled your radius all you would have to do is divid your diameter by 2nthen you get your radius

Answer 2

2pi r = 140

r = 140/2pi

r = 70/pi

please write pi as the symbol when you record the answer, I’m just limited to type pi because my keyboard doesn’t type the symbol.
