Hello there, to answer this question, one must know the formula of area of a circle.
1. Use formula for area of circle to find area of base of cylinder
2. Multiple area of base with height of cylinder for volumne
Area = pi * r * r
Cylinder A:
Area: pi * 6 * 6 = 113.1 inches square
Volumne = Area * Height = 113.1 * 4 = 452.4 inches cube
Cylinder B:
Area: pi * 5 * 5 = 78.54 inches square
Volumne = Area * Height = 78.54 * 5 = 392.7 inches cube
Cylinder C:
Area: pi * 4 * 4 = 50.27 inches square
Volumne = Area * Height = 50.27 * 6 = 301.62 inches cube
From bottom to top - corn syrup, glycerol, wafer and corn oil at the top, because the densiest ones sink
Answer:
4² + 5² = x²
Step-by-step explanation:
From the picture, the height of the staircase is:
h = 20 ft -15 ft = 5 ft
And the distance between the staircase and the building is 4 ft.
A right triangle is formed, where the distance between the staircase and the building (4) and the height of the staircase (5) are the legs, and the length of the staircase (x) is the hypotenuse. Using Pythagorean theorem:
4² + 5² = x²
