Barney was first created in 1987 by Sheryl Leach, who was looking for a way to entertain her then 2 year old son, Patrick. Originally, Barney was going to be a blanket. When that was proven to be too hard, he became a teddy bear who came to life. Patrick was fascinated by a dinosaur exhibit at a museum, particularly the Tyrannosaurus rex. In response, Sheryl made Barney a T. Rex. Kathy Parker, a fellow teacher-turned-mother who had helped Sheryl create the character, agreed to the change, but on the condition that he was not to appear menacing (a realistic t-rex would have scared her daughter Kaitlin). In the end, he was colored purple to appeal to both genders (Leach had a thing for the color purple as well) and had his features softened (i.e. "toe balls" in place of claws).

the answer is 489

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
