Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:
Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
Hello!
To find the volume of a cone, use the formula: V = 1/3πr²h.
In the photo, the height is 6 units, and the diameter is 8 units. Since the radius is half the diameter, then the radius is 4 units.
V = 1/3π(4)²(6)
V = 1/3(6)(16)π
V = 2(16)π
V = 32π
V = 100.5309... This can be rounded to about 100.5.
Therefore, the volume of this cone, is about 100.5 units³.
Answer:
28.57%
Step-by-step explanation:
Given data
Initial cost =$28
Final cost =$36
Required
The percentage change in cost
Percent change =final - initial/initial*100
Substitute
Percent change =36-28/28*100
Percent change =8/28*100
Percent change =0. 2857*100
Percent change =28.57%
<span>The expression 2x + 50 represents the elevation above sea level of the climber. It can be written as a function as follows:
f(x) = 2x + 50 where f(x) is the height and x is time.
We can obtain the initial height when we set time 0 in which the climber has not started climbing yet. Therefore, the initial height of the climber would be 50 meters above sea level.</span>
