Answer:
14130 ft^3
Step-by-step explanation:
The formula for the volume of a cone of radius r and height h is
V = (1/3)*pi*r^2*h.
Here, V = (1/3)(3.14)(15 ft)^2*(60 ft) = 20*3.14*225 ft^3 = 14130 ft^3
Since you said the height of your chair and you desk, chair would go first when subtracting.
C= chair
c - 29.75 = -10.25
+ 29.75 = + 29.75
c= 19.5
So, you chair is 19.5 (19 1/2) inches tall.
