Answer:
<u>The volume of the pyramid is 16 m³ (cubic meters)</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Length and width of the square pyramid = 4 m
Height of the square pyramid = 3 m
2. What is the volume of the square pyramid?
Let's use the formula of the volume of a pyramid:
Volume = (Length * Width * Height)/3
Volume = 4 * 4 * 3/3
Volume = 48/3 (Dividing by 3)
<u>Volume = 16 m³(cubic meters)</u>
In terms of diameter (d), the area (A) of a circle is given by the formula
A = (π/4)d²
You have d=20 yd, so the area of the circle is
A = (π/4)×(20 yd)² . . . . substitute the given information into the formula
A = 100π yd² . . . . . . . . do the arithmetic
A ≈ 314.16 yd²
B.x=$6.40. You do 32÷5 to figure out what 1x equals and that's $6.40
