(a)
To calculate: The Volume of sphere with radius (r)=3
(a)

Answer to Problem 1PSA
The volume of the sphere (V)=113.1 units3
Explanation of Solution
Given:
Radius, r is 3 units.
Formula used:
V=43πr3
Calculation:
Putting value of r in formula of volume
V=43(33)V=113.1(unit3)
(b)
To find: The Volume of sphere with diameter 18 units
(b)

Answer to Problem 1PSA
3053.63 unit3
Explanation of Solution
Given:
Diameter is 18 unit, hence radius(r) will be half of diameter ,i.e. 9units
Formula used:
V=43πr3
Calculation:
Putting value of r in formula of volume, V
V=43(9)3V=3053.63 unit3
(c)
To find: The Volume of sphere with radius 5 units
(c)

Answer to Problem 1PSA
524.6 unit3
Explanation of Solution
Given:
Radius of sphere is 5 units.
Formula used:
V=43π(r)3
Calculation:
Putting value of r in formula of volume, V
V=43(5)3V=523.6 unit3
