Question

Volume of spheres and cones??????????

Answer 1

Answer:

The correct answer is option d. 179.503 cub in

Step-by-step explanation:

Formula:

Volume of Sphere = (4/3)πr³

r - radius of sphere

To find the volume of sphere

From the figure we get,

diameter d = 7 in

radius r = d/2 = 7/2 = 3.5 in

Volume = (4/3)πr³ =  (4/3) * 3.14 * (3.5)³  = 179.503 cub in

Therefore,the correct answer is option d. 179.503 cub in

Answer 2

Answer:

The volume of sphere is 1436.76 cubic inches

Step-by-step explanation:

The volume of sphere is given by

V = 4/3 * pi * r³

By putting the values

V = 4/3 * 3.14 * 7³

V = 4/3 * 3.14 * 343

V = 1436.76 cubic inches
