Answer:
94.6m³
Step-by-step explanation:
The diagram shown in this question is a trapezoidal prism.
The volume of a trapezoidal prism is calculated as:
L × H × (P + Q/2)
Where L = Length = 4m
H = Height = 4.3m
P = Base width = 8m
Q = Top width = 3m
The volume of the trapezoidal prism =
4 × 4.3 ×(8+3/2)
=4 × 4.3 ×(11/2)
= 94.6m³
Therefore, the volume of the trapezoidal prism to the nearest tenth = 94.6m³
Answer:
P = 61.70 feets
Step-by-step explanation:
Based on the information given :
For fencing , We need to calculate the perimeter of the semicircle ;
Perimeter of a semicircle is given as :
P = πr + 2r
P = perimeter ; r = Radius = 12 feets
P = 12π + 2*12
P = 12π + 24
P = 61.699111 feets
P = 61.70 feets
To. Obtain how much.
We multiply the perimeter by the cost per feet.
