Step-by-step explanation
<em>The volume of cone is 7068.58 ans</em>
Let x and y be width and length of the plot to be fenced. Therefore,
Area (A) = xy m^2
If the side bordering the river is x, then
Circumference (C) = 8500 = x+2y => x = 8500-2y
Substituting for w in the equation for A;
A = (8500-2y)y = 8500y -2y^2
For maximum area, derivative of A with respect to y is 0. That is;
dA/dy = 0 = 8500 -4y => 4y = 8500 => y = 8500/4 = 2125 m
And, x = 8500-2y = 8500 -2*2125 = 4250 m
Therefore,
One side = 4,250 m and second side = 2,125 m.
Largest area, A = 4250*2125 = 9,031,250 m^2

Hey there!
Let's plug these values into the formula.
1/2(7(4))
1/2(28)
14
Therefore, our area would be 14 sq cm.
I hope this helps!
Given that after a discount of 40% a furniture was bought for $438. The original price of the furniture will be calculated as follows:
discount=40%
new percentage price=100-40=60%
Original percentage price=100%
New buying price=$438
therefore, the original price was:
100/60×438
=$730
The original price was $730
