Question

Find the circumference of the circle if the square has an area of 144 m2. Give your answer to the nearest tenth. Use 3.14 form

Answer 1

Circumference of Circle = 2πr
Area of circle = πr²
144 = 3.14 * r²
r² = 144/3.14
r² = 45.85
r = √45.85
r = 6.77
 
Circumference = 2πr = 2*3.14*6.77
Circumference = 42.51 m²

So, your answer is 42.51 m²
