What's the diameter of a circle if it's area is 153.86m2?

Since the area of a circle is A = pi x r^2, and you know A, you can divide 153,86 by pi. What gives you 48,97515909. That means r^2 = 48,975 ... you can calculate r by taking the square root of your answer, that gives you 6,998225424. And since the diameter is two times the radius, the diameter would be 13,99645085. I think.

Answer:It's about 7, if needed ungrounded 6.99822542422

Step-by-step explanation: Take 158.86m2 and divide by pi, (48.975 ...) then square root your answer.
