What is the area of a circle that has 0.5mm

A = πr2 = π(d2)2

A = C24π

π = 3.1415

A = area

C = circumference or perimeter

r = radius, d = diameter

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
