13.6 if you meant .4% of 34 because you multiply them. move the decimal point and solve it
Circumference = 2(pi)r
Area = (pi)r^2
r = 5
5 * 2 = 10
Circumference = 10π
5 * 5 = 25
Area = 25π
Using 3.14 as pi substitute:
5 * 3.14 = 15.7
15.7 * 2 = 31.4
Circumference = 31.4
5 * 5 = 25
25 * 3.14 = 78.5
Area = 78.5
That is really easy how don't you know
area of a square= 702.25
A= side square
let's take side of a square= a
therefore,
702.25= a^2
a= √702.25 = 26.5
perimeter (P) of a square= 4a
P = 4x 26.5= 106
so perimeter of a square is 106
