Answer:
30 in^2
Step-by-step explanation:
The formula for finding the area of a trapezoid is A=a+b/2 x h
In this case, a=5, b=10, and h=4
When you input those values into the formula and solve for A, you get A=30

Answer:
It is 2πrh + 2π
Step-by-step explanation:
What are we supposed to do....
Y
y=ax
where a is a constant of proportionality;
y=20, x=4
20=4a
a=20/4
a=5
y=5x
The constant of variation is 5
The length of the windshield wiper to the nearest inch is 24 inches
<h3>How to calculate the area of a sector</h3>
The formula for calculating the area of a sector is given as:
A = r²β/2
r is the length of the wiper
β is the subtended angle
Given the following
A = 500.3 square in
β = 98 degrees = 98pi/180 = 49pi/90
Substitute
500.3 = r²49pi/180
500.3 = 153.86r²/180
153.86r² = 90054
r² = 585.298
r = 24.19
Hence the length of the windshield wiper to the nearest inch is 24 inches
