Answer:
π = 198/63
Divide the distance traveled by the wheel to guess the value or estimate the value of π.
Step-by-step explanation:
Height of the wheel: Diameter of the circle
Perimeter of the circle = π*diameter of the circle
Divide the diameter of the circle by the perimeter of the circle.
π = 198/63

Step-by-step explanation:
The answer is 10 cm
Imagine cement cover as a rectangle which volume is 660,000,000 cm3. So this rectangle has width (w = 60m), length (l = 110m), and height (h = ?). The height of the rectangle is actually a thickness of the cement layer. So, we will use the formula for the volume (V) of the rectangle to calculate the thickness:
V = w · l · h
It is given:
V = 660,000,000 cm³
w = 60 m = 60 · 100 cm = 6,000 cm
l = 110 m = 110 · 100 cm = 11,000 cm
h = ?
Using the formula: V = w · l · h
660,000,000 = 6,000 · 11,000 · h
660,000,000 = 66,000,000 · h
⇒ h = 660,000,000 ÷ 66,000,000 = 10 cm
