Find the area of the shape with a radius of 2

A = pi units^2

or A = 3.14 units^2

Step-by-step explanation:

This is 1/4th of a circle.  Take the area of a circle and multiply by 1/4

A = 1/4 pi  r^2

The radius is 2

A = 1/4 pi *2^2

A = 1/4 *pi * 4

A = pi

If we use the approximation that pi = 3.14

A = 3.14

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
