The circumference of a circle is 282.54282.54 m. What is the approximate area of the? circle? Use 3.14 for p.

Question

i need to know the answer for this problem

 

Answer 1

Formula for the circumference of a circle is C = 2πr = πd (r = radius, d = diameter).

Formula for the area of a circle is A = πr².

 

To solve this problem, you need to find r, then use the area formula to find A.

 

Find r: C = 282.54282 m. C = 2πr, so r = C/(2π) = 282.54282/(2·3.14) = 44.96808644 m. (A calculator was used.)

 

Find A: A = π(44.96808644)² = (3.14)(44.96808644)² = 6352.705 m².

 

The measurements you gave have too much accuracy, so I am not sure how you want the answer rounded.
