Answer:
707.9 cm³
Step-by-step explanation:
What is the volume of a spherical shell with inner radius 7 and outer radius 8?
The formula for the volume of a sphere is given as;
= 4/3 × π × r³
From the above question:
inner radius 7 and outer radius 8
Hence, the volume of a sphere with
inner radius 7 and outer radius 8 is calculated as:
V = (4/3 × π × 8³ ) - (4/3 × π × 7³)
V = 4/3 × π ×(8³- 7³)
V = 4/3 × π × (512 - 343)
V = 4/3 × π × 169
V = 707.9055446 cm³
V = 707.9 cm³
