Answer:
Step-by-step explanation:
perimeter = l + b + l + b or 2(l + b)
92 = 19 + 19 + 2b
92 = 38 + 2b
2b = 92 - 38
2b = 54
b = 54 / 2
b = 27
breadth or width of the triangle = 27
length = 19
Answer:
dh/dt = 0,07 ft/min
Step-by-step explanation:
The swimming pool has the shape of right circular cylinder, therefore its volume is
V(c) = π*x²*h
Where x is the radius of the base and h the height
We take differentiation on both sides of the equation to get:
dV/dt = π*x²*dh/dt
The rate of change in height of water in the pool, is independent of the height of the water, since the pool is a right crcular cylinder, and dV/dt is constant at 8 ft³/min.
Then:
8 = π*x²*dh/dt
dh/dt = 8 / π*x²
dh/dt = 8/113,04
dh/dt = 0,07 ft/min

The last answer choice is correct. Hope this helps!
Answer:
The area of the parallelogram is 29 square units.
Answer:
Step-by-step explanation:
V = (4/3)(3.14)(3^3)
V = 4/3 * 27 * 3.14
V = 36 * 3.14
V = 113.04
