Question

suppose a hole of radius 1 is bored through a sphere of radius 2. what is the volume of the resulting shape

Answer 1

21.77

Explanation:

Applying,

V = (4/3)π(R²-r²)³/²................. Equation 1

Where V = Volume of the resultant shape, R = radius of the sphere, r = radius of the hole bored, π = pie

From the question,

Given: R = 2, r = 1

Constant: π = 3.14

Substitute these values into equation 1

V = 4/3(3.14)(2²-1²)³/²

V = (12.56/3)(3)³/²

V = 4.19(5.196)

V = 21.77
