Question

Find the volume of hemisphere having radius 31cm​

Answer 1

Step-by-step explanation:

Given Find the volume of hemisphere having radius 31 cm

• So given radius r = 31 cm
• We need to find the volume of hemisphere.
• So volume of hemisphere is given by
•                    V = 2/3 π r^3
•                      V = 2/3 x 22/7 x (31)^3
•                      V = 2/3 x 22/7 x 29791
•                     V = 44 x 29791 / 21
• Volume of hemisphere = 62419.23 cm^3
• Or if radius r = 3 cm we get
•                         V = 2/3 x 22/7 x 3^3
•                             = 2/3 x 22/7 x 27
•                             = 44 x 27 / 21
•                             = 1188 / 21
•                             = 56.57 cm^3
