Hey there! :)
The formula for finding volume of a sphere is: 4/3 · π · r³
Diameter = 2x radius
Radius = ½ diameter
22 ÷ 2 = 11
Radius = 11
11³ = 11 × 11 × 11 = 1331
1331 × 4/3 = 5324/3 = 1774 2/3
1774 2/3 × π = 5575.3
The volume of the sphere is 5,575.3 m³
Hope this helps :)
(By the way, I used pi instead of 3.14 )
