V=pi*r^2*h/3
60*pi = pi*r^2*h
180 = r^2*h
middle school means (most likely r and h are integers)
r=6, h=5, d=12
Answer:
it would be $58.50
Step-by-step explanation:
The new dimension of the rectangle are as follows;
<h3>How to find the new dimension of the rectangle?</h3>
The new dimension of the rectangle can be found as follows;
The sides of a square are equal.
Therefore,
let the side of the square = x
Hence,
length = x + 3
width = x + 1
area of rectangle = lw
where
Therefore,
24 = (x + 3)(x + 1)
24 = x² + x + 3x + 3
24 = x² + 4x + 3
x² + 4x + 3 - 24
x² + 4x - 21 = 0
(x - 3)(x + 7)
Therefore,
x = 3 or -7
It can't be negative. Hence, x = 3 ft
Therefore, the new dimension of the rectangle are as follows;
- x + 3 = 3 + 3 = 6 ft
- x + 1 = 3 + 1 = 4 ft
