Answer:

See below.

Step-by-step explanation:

Pi ( written as the Geek letter π) is a universal constant found by dividing the circumference of a circle by it's diameter. So if you measure the diameter of a circle you can calculate it's circumference by multiplying by π.

Circumference = π * diameter.

It's value to the nearest hundredth is 3.14 but its actual value is a decimal number that goes on without bounds. That is in Maths it is irrational and can't be written accurately as a fraction.

Answer:

Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter.

Answer:

Step-by-step explanation:

law of sines

Sin(A) / a = Sin(B)/b

where A = 24

a=BC

B= 59

b =AB

then

Sin(24)/a =Sin(59)/19

0.4067366 / a = 0.8571673 / 19

0.4067366 / a = 0.045114

0.4067366 / 0.045114 = a

9.015 = a

BC = 9.0 mi

HELP QUICK LOTS OF POINTS

Answer:

see attached

Step-by-step explanation:

When the sequence of sides (shortest to longest, for example) remains the same (CW or CCW), then the number of reflections is even, possibly zero. The figure will have been translated if all of the corresponding sides retain their original direction, otherwise rotation is involved.

If the sequence is reversed, as in the upper right and lower left figures, then reflection is involved. The line of reflection will be the line through the midpoints of the segments connecting corresponding vertices.
