Part 1
The volume of the hemisphere is

1 answer

calculated using the formula:

V = (2/3) * π * r^3

Given that the radius, r = 21 m, we can substitute this value into the formula:

V = (2/3) * 3.14 * (21)^3
V = (2/3) * 3.14 * 9261
V = 2.09 * 9261
V = 19353.54 m^3

Therefore, the volume of the hemisphere with a radius of 21 m is approximately 19353.54 cubic meters.
