To find the volume of a hemisphere, we use the formula V = (1/2) * (4/3) * pi * r^3.
Given:
Radius, r = 11 cm
Value of pi, pi = 3.14 (approximation)
Substituting the given values into the formula:
V = (1/2) * (4/3) * 3.14 * (11^3)
V = 2/3 * 3.14 * (11^3)
V ≈ 2/3 * 3.14 * 1331
V ≈ 2.094 * 1331
V ≈ 2785.414
Rounding the answer to the nearest whole number:
V ≈ 2785 cm^3
Therefore, the answer is option B. 2786 cm^3.
