A dog is leashed to a point in the center of
a large yard. If the leash is 18.8 feet long,
what is the total area of the region the dog
is able to explore?

1109.80 ft²

Step-by-step explanation:

In this case apply the formula for finding area of a circle where the rope tied to the dog will represent the radius of the circle area for the region the dog can explore.

Area of a circle= πr²

radius= r= 18.8 ft

Area of a circle= 3.14*18.8*18.8=1109.80 ft²

a

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
