Finding the circumference of a circle whose area is 452.16 square meters

Hey user!

your answer is here..

given the area of the circle is = 452.16m²

therefore πr² = 452.16m²

==> 3.14 × r² = 452.16m²

==> r² = 452.16/3.14

==> r² = 144

==> r = √144

==> r = 12m

the radius of the circle is 12m.

now, circumference of the circle = 2πr

= 2 × 3.14 × 12.

= 75.36m

cheers!!

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
