The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
Answer:
Circumference ≅ 195 mm
Step-by-step explanation:
The circumference of a circle is equal to: 
Since
we can replace that in the circumference equation giving us:

We know Diameter = 622 mm and pi = 3.14 so:

If polygons ABCD and EFGH are similar, then their perimeters most likely are also similar. Polygon EFGH also have the same perimeter with polygon ABCD. Having similar polygons is referred as congruent polygons. <span>Two figures are said to be congruent when they have the same shape and
size or if one object is a mirror image of the other object.<span> </span></span>
It would be 33.333333% Likely to be a boy or a girl.
