Question

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

tenth of a cubic meter?

Answer 1

13.3

Explanation:

i got it right

Answer 2

volume of the hemisphere ≈13.3 m³

Explanation:

To find the volume of the hemisphere, we will follow the steps below;

volume of a hemisphere = volume of a sphere/2

=
`(4)/(3)`πr³ /2

=
`(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 =
`(2)/(3)`πr³

≈
`(2)/(3)`×3.14 ×1.85³

≈13.3 m³

Therefore, volume of the hemisphere ≈13.3 m³
