Ответ:
29,225.78 m^3 to the nearest hundredth.
134.4 m^3.
Step-by-step explanation:
The building:
The area of the floor = area of the square + 3/4 * area of the circle
= 22^2 + 3/4 π 11^2.
The volume of the building =
38 * (22^2 + 3/4 π 11^2)
= 29,225.78 m^3.
The greenhouse:
The sides consist of 2 pairs of trapezoids.
Area of a side = 2 * (0.6/2)(0.7 + 2.1) + 2 * (1.4/2)(2.1 + 2.7)
The length is 16 m so:
Volume = 16 * [ 2 * (0.6/2)(0.7 + 2.1) + 2 * (1.4/2)(2.1 + 2.7) ]
= 134.4 m^3.
Ответ:
left 29226 Right 134
Step-by-step explanation:
volume=base*height
(22*22+(11)^2 *3.14*3/4)*38=29226
((1.4+0.6)*2*0.7+1.4*2*1.4+0.6*1.4+0.6*1.4))* 16=134
