Question

The circumference of a circle is 119.32 centimeters. What is the circle's area?

Use 3.14 for ​.

Answer 1

`\text{We need to find the area of the circle with its circumference given}\\\\\text{The equation for this is:}\\\\A=(C^2)/(4\pi)\\\\\text{In this case, we would use 3.14 for pi, so your equation is:}\\\\A=(C^2)/(4(3.14))\\\\\text{Plug in your circumference and solve:}\\\\A=(119.32^2)/(4(3.14))\\\\A=(14,237.2624)/(4(3.14))\\\\A=(14,237.2624)/(12.56)\\\\\text{Divide:}\\\\A=1,133.54\\\\\boxed{\text{The area is 1,133.54}\,\,cm^2}`
