The base of the cylinder is a circle in which the area is calculated through the equation,
A = πr²
We are given that area is 25π in². From this and the equation above, the value of r is equal to 5 in. Using this calculated value as the height, the volume of the cylinder is,
V = Bh
where B is area of the base and h is height.
V = (25π in²)(5 in) = 125π in³
or also equal to,
V = 392.7 in
Fist you have to find the volume which is 24 x 18 x 5= 2160 feet.
Then the dump truck can only take 8 cubic yards so then you have to make the 2160 feet into yards.
There are 3 feet in one yard so 2160/3=720
so now there are 720 yards and since the dump truck can only take 8 yards a trip then it would take 90 trips/dumps to empty out the area for the pool.
720/8=90
Hope this helps
We need the radius to find the area of sector.
radius = 20/2 = 10
Area of sector:
πr²(x/360) = x is the central angle in degrees.
π(10)²(36/360)
10π in²
Hope this helps :)
A parabola is a curve where any point is at an equal distance from:

Answer:
just move the decimal to the right two place, for two zeroes. The answer is 1490.
Step-by-step explanation: Just simply multiply 14.9 by 100.
