B.
Step-by-step explanation:
Given:
A spherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters.
diameter of Sphere = 20 centimeters
hence radius = half of diameter =
Hence we need to find the volume of sphere.
Volume of sphere =
Here r is the radius of the circle.
Hence Volume of sphere =
Hence Option B is the correct answer.
Vincent’s proportion is incorrect. His corresponding parts are not in the same position. The heights and bases are in different positions.
