Hello!

To find the circumference, you multiply the diameter by pi. We will do so below.

2.5 $\pi$ ≈7.85

a. 7.85 feet

___________________________________________________

To find how many rotations it will take to travel a mile, we will need to divide our mile by our circumference.

5,280/7.85≈672.61

b) 672.61

I hope this helps!

The circumference would be 7.85

And b would be 672.611465 because each time you divide by 7.85 ft

Answer:

StartRoot 2 squared + 6 squared EndRoot

Step-by-step explanation:

we have

A(4,3) and B(-2,1)

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the given values

$AB=\sqrt{(1-3)^{2}+(-2-4)^{2}}$

$AB=\sqrt{(-2)^{2}+(-6)^{2}}$

$AB=\sqrt{40}\ units$

therefore

StartRoot 2 squared + 6 squared EndRoot

Which polygons are congruent?

bonufazy [111]

Two polygons are congruent if they are the same size and shape - that is, if their corresponding angles and sides are equal. Move your mouse cursor over the parts of each figure on the left to see the corresponding parts of the congruent figure on the right.
