The area of a circle = PI * radius^2
area = 3.14159 * 16
area = 50.265
area = PI * 16

We have to determine the area of the shaded section, which is (3 / 4) of the circle. The unshaded section is occupied by a 90 degree angle which is (1 / 4) of a circle (All circles contain 360 degrees).
So the shaded section =
50.265 * (3 / 4) = 37.699
OR
16 * PI * (3 / 4) = 12 * PI

Find the total area of the entire figure. *

bonufazy [111]

Answer:

392.5 in²

Step-by-step explanation:

This figure is consists of a trapezium and a rectangle.

So, to find the total area of the figure you have to find the area of the trapezium and the rectangle separately and add them together.

Let us find now.

Area of the Trapezium

Area = $\frac{1}{2}$ × ( sum of the parallel sides ) × height

Area = $\frac{1}{2}$ × ( 9 + 20 ) × 5

Area = $\frac{1}{2}$ × 29 × 5

Area = $\frac{1}{2}$ × 145

Area = 72.5 in²

Area of the rectangle

Area = Length × Width

Area = 20 × 16

Area = 320 in²

Total area of the figure

Total area = Area of the trapezium + Area of the rectangle

Total area = 72.5 in² + 320 in²

Total area = 392.5 in²

Hope this helps you :-)

Let me know if you have any other questions :-)

Ariel was told the x intercept and the y intercept of a line with a positive slope. Yet, it was impossible for Ariel to find the

alexdok [17]

A line has the following standard equation form:

y = m x + b

where m is the slope and b is the y intercept

So if Ariel cannot find the slope, then this would only mean that m = 0, there is no slope. And hence the line is either a straight vertical line or straight horizontal line.

Answer:

There is no slope

Ewans flight is schheduled to travel 1,750 in 3.5 hours . at what rate does it travel per hour

Karo-lina-s [1.5K]

Answer:

It travel at the rate of 500 miles per hour.

Step-by-step explanation:

Given:

Ewans flight is scheduled to travel 1,750 miles in 3.5 hours.

Now, to find the rate it travel per hour.

Distance = 1,750 miles.

Time = 3.5 hours.

So, to get the rate we put formula:

$Speed=\frac{distance}{time}$

$Speed=\frac{1750\ miles}{3.5\ hours}$

$Speed=500\ miles\ per\ hour$

Therefore, it travel at the rate of 500 miles per hour.
