Answer:
28 units^2
Step-by-step explanation:
1. First, let's divide this figure into two shapes: a square and a trapezoid. (Look at the image below explanation for division).
2. Next, we should know the area formulas of the square and trapezoid.
- Square:
, where s = side 
, where a and b = top and bottom and h = height
3. Solving Area of Square and Trapezoid
. Area of square is 16
. Area of trapezoid is 12.- 16 + 12 = 28
Therefore, the area of the figure is 28 units^2.
Answer:
1 min 45 sec
Step-by-step explanation:
First convert 14 min to seconds.
14 x 60 = 840s
Now we can use ratios to find the answer
840s : 800m
Divide both sides by 8
105s : 100m
105s is 1 minute and 45 seconds
Answer:
Volume of Pipe is 226 ft³.
Step-by-step explanation:
Given:
Cylindrical Shape Pipe having
Height = 18 ft
Diameter = 4 ft
∴ 
To Find:
Volume of Pipe = ?
Solution:
Formula for Volume of Cylinder is given by
Substituting the given values we get
Volume of Pipe is 226 ft³.
When the ball hits the ground, the height is 0.
0 = 100 - 16t²
0 = (10 - 4t)(10 + 4t)
0 = 10 - 4t or 0 = 10 + 4t
4t = 10 or -4t = 10
t = 
or t = 
Time cannot be negative (unless you have a time machine) so disregard
Answer: t = 
= 2.5 seconds
There are no numbers for this, thus you will have to use the quadratic formula.
