Answer:

63.0

Explanation:

area of circle = πr²

area of quarter circle = πr²/4

area of triangle = bh/2

area of shaded quarter circle:

πr²/4 = (3.14159)(7²)/4 = 38.4845 units²

area of shaded triangle:

bh/2 = (7)(7)/2 = 24.5 units²

total shaded area = 38.4845 units² + 24.5 units² = 62.9845 units²

Answer: 63.0 units²
