Question

What is the volume of a hemisphere with a diameter of 3.7 m, rounded to the nearest

Answer 1

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

                                         = $\frac{4}{3}$πr³  /2

                                         =$\frac{2}{3}$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 = $\frac{2}{3}$πr³

                                          ≈  $\frac{2}{3}$×3.14 ×1.85³

                                           ≈13.3 m³

Therefore, volume of the hemisphere  ≈13.3 m³
