Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
Answer
Step-by-step explanation:
A=2πrh+2πr2=2·π·3·6+2·π·32≈169.646
To find the area of a polygon you have to write the formula of it which is area= 1/2 x perimeter x apothem . hope this helps
Round to the nearest significant number
275,000,000 = 2.75^8
2.75^8 is your answer

A reasonable function is W = 7F + 5000
Where W is the weight of the plane and F is the number of gallons of fuel.
The domain is the set of possible values for F. That is from 0 (empty tank) to 400 (full tank).
So the domain is F = [0,400], or what is equivalente 0 ≤ F ≤ 400.
The range is the set of values of W.
The minimum value of W is when F = 0 => W = 7(0) + 5000 = 5,000.
The maximum value of W is when F = 400 => W = 7(400) + 5000 = 7,800
So the range is W = [5,000 ; 7,800], pr 5000 ≤ W ≤ 7,800.
