PLZ HLP! A dog is leashed to the corner of a house. How much running area does the dog have? Round your answer to the nearest square foot, if necessary.

The area of a circle is area = pi x r^2

The full area = 3.14 x 20^2 = 1256 square feet.

The corner forms a 90 degree angle so the dirt area is 3/4 of a full circle.

Answer = 1256 x 3/4 = 942 square feet

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
