Answer:
6 ft above ground.
Step-by-step explanation:
The roller coaster starts from an elevation of +20 feet from the ground.
Now, it first corns 78 ft, then drops 85 ft.
So, the final elevation will be (20 + 78 - 85) = 13 feet above the ground on the second hill.
Again, it climbs 103 ft. and drops 110 ft. and finally his elevation will be = 13 + 103 - 110 = 6 ft above ground. (Answer)
Well if the data is related to 8 cm by 12cm(it means 4cm of radius and 12 of height)and you already have pi so what you need is to use the formula <span>V=π*r^2*(h/3) and replace the data. After you do this you can see that the closest is 339 cm3. Hope this helps a lot </span>

Step-by-step explanation:
Answer:
Total cost of cementing the path = Rs. 17,000.
Step-by-step explanation:
Let the square garden be ABCD
Let the region inside the garden (ABCD) be WXYZ.
<u>Given the following data;</u>
Length of sides of ABCD = 90m
Width of path = 5m
Cost = Rs. 10 per m²
Area of ABCD = 90 * 90
Area of ABCD = 8100m²
<em>To find the area of WXYZ;</em>
WX = WZ = 90 - (5 + 5)
WX = WZ = 90 - 10
WX = WZ = 80m
Area of WXYZ = WX * WZ
Substituting into the equation, we have;
Area of WXYZ = 80 * 80
Area of WXYZ = 6400 m²
Area of path = Area of ABCD - Area of WXYZ
Area of path = 8100 - 6400
Area of path = 1700 m²
Total cost of cementing the path = Area of path * cost
Total cost of cementing the path = 1700 * 10
<em>Total cost of cementing the path = Rs. 17,000</em>
