Answer on Geometry Question for jennifer
D = 1.5 ft
H = 2.5 ft
S = 100 ft²
D = 2*R ==> R = 1.5/2 = 0.75 ft - the radius of a pot.
The surface area of a pot is
A = 2*pi*R^2 + 2*pi*R*H = 2*pi*0.75^2 + 2*pi*0.75*2.5 ≈ 15.3154 ft².
So, two flower pots with two coats of paint need
V = (A*2*2)/S = 15.3154*4/100 = 0.6126 litres of paint.
So, one litre of paint is enough to paint the two flower pots with two coats of paint.
