Answer: 1️⃣ 40
Step-by-step explanation:
<em>x - is the side of the square</em>
<em />
<em />
<em>Find the perimeter of the square.</em>
<em>Perimeter of the square = 4 × 10 cm = 40 cm</em>
<em />
The total area of the frame is therefore 2(4x) + 2(4)(x-8) = 8x + 8x - 64 = 16x - 64
Volume of a cone formula: V = πr²*h/3
V = volume
r = radius
h = height
Solve with the given values.
V = π(7)²*19/3
V = π(49)*19/3
V = 153.86*19/3
V = 974.94...
Round to the nearest one.
974.94... → 975.0
Therefore, the answer is 975.0yd³
Best of Luck!

Answer:
The combined amount is $14871.21.
Step-by-step explanation:
It is given that, the total yearly income of gentry family is <em>$29742.42</em>
<em>The % charge on income for food is 20%.</em>
<em>The % charge on income for housing is 30%.</em>
The amount in dollar from % form is given by,
= 
For annual food,
= 
= $5948.484
For housing budgets,
= 
= $8922.726
Thus the combined amount is,
= 
= $14871.21
