Formula for Area From Circumference

You can also convert the original equation to calculate the area of a circle from its circumference, c. We know that π = c/d; rewriting this in terms of d you have d = c/π. Substituting this value for d into A = π(d2)/4, we have the modified formula: A = π((c/π)2)/4 = c2/(4 × π).

Step-by-step explanation: It is a constant ratio of the circumference to the diameter. This means that π = c/d, where c is the circumference of a circle and d is the diameter of the same circle. Pi= about 3.14 the answer is 25pi in ^2

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

first one because it can't have a fraction in it
