Please help me with this question I will mark you as brainiest!

7.72 cm²

Step-by-step explanation:

Subtract the area of the circle from the area of the square for shaded area.

area of square = 6² = 36 cm²

area of circle = πr² ( diameter of circle is 6, thus radius is 3 )

area = 3.14 × 3² = 3.14 × 9 ≈ 28.28 cm²

Shaded area = 36 - 28.28 = 7.72 cm²

B

Step-by-step explanation:

V=1/3Bh

v=1/3s^2 (1/2s)

v=1/6s^2
