Brianna cut her pancake in half to share with friend. If the pancake's distance from one side of the pancake to other side was 8 inches, how much pancake does Brianne get to eat.

Brianne gets 25.12 inches² of pancake.

Step-by-step explanation:

Assuming the pancake to be a circular shape.

If the pancake's distance from one side of the pancake to other side was 8 inches, then diameter of circle = 8 inches. It means radius = 4 inches.

Brianne cut her pancake in half to share with friend. It means Brianne gets half-circular shape. So we need to find area of half-circle.

Area of half-circle = (1/2) πr² = (1/2) x 3.14 x 4² = 1.57 x 16 = 25.12 inches².

Hence, Brianne gets 25.12 inches² of pancake.
