A hemispherical bowl has a radius of 3.5 cm. What would be the volume of water it would contain?
Answer:
Solution:
The space that a hemisphere takes up is referred to as its volume. The volume of a thing determines how much space it takes up. Half of a whole sphere, a hemisphere is a 3D object. As a result, a hemisphere's volume is equal to half that of a sphere.
Given radius of the hemispherical bowl, r = 3.5 cm = 7/2 cm
Volume of the hemisphere = (2/3)π r3
= (2/3)×(22/7)×(7/2)3
= 11×49/6
= 539/6
= 89\ \frac{5}{6}\ cm^3
Hence the volume of the hemispherical bowl is
89\ \frac{5}{6}\ cm^3
