Answer:
volume of the hemisphere ≈13.3 m³
Step-by-step explanation:
To find the volume of the hemisphere, we will follow the steps below;
volume of a hemisphere = volume of a sphere/2
= πr³ /2
=πr³
from the question given, the diameter is 3.7 m, but diameter = 2×radius
radius = diameter /2 = 3.7/2 =1.85 m
π is a constant = 3.14
volume of a hemisphere = πr³
≈ ×3.14 ×1.85³
≈13.3 m³
Therefore, volume of the hemisphere ≈13.3 m³
