Volume of prisms, but what is this?

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

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.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
