Answer:
56.5 cu.in
Step-by-step explanation:
Diameter is 6 inches,then radius(r)=3 inches
volume of hemisphere=2/3πr^3
=2/3×3.14×3×3×3
=2×3.14×3×3
=2×3.14×9
=56.52 cu.in
To find it directly
A = 2 pi r h
A is proportional to rh
factor 2
A is multiplied by 2 * 2 = 4
factor 3
3 * 3 =9
factor 5
5 * 5 = 25
factor 10
10 * 10 = 100
(b) the increase in A by factor x is x^2
c(20)^2 = 400
