What is the area of a circle that has the radius of 4?

4^4 = 16

16 x 3.14 = 50.24

Step-by-step explanation:

Formula of an area of a circle is:

radius squared x pi(3.14 or 22/7 or whatever they use for pi)

Step-by-step explanation:

A= 50.27

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
