Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenths place.
Answers
Answer:
153.1 square unit
Step-by-step explanation:
for rectangle
length = 16
breadth = 8
area of rectangle = l*b
=16*8
=128 square unit
semicircle
diameter =8
area of semicircle =πd^2/8
=3.14 * 8^2 /8
=3.14 *64/8
=200.96/8
=25.12 square unit
area of the givem figure = area of rectangle + area of semicircle
=128 + 25.12
=153.12
=153.1 square unit
Final answer:
To find the area of the figure made up of a rectangle and a semicircle, calculate the areas of both shapes and add them together. Use the formula for the area of a rectangle, and calculate the area of the semicircle by finding half the area of a full circle with the same radius. Finally, sum up the areas to find the total area of the figure.
Explanation:
To find the area of the figure, we need to find the areas of the rectangle and the semicircle, and then add them together. The area of the rectangle is found by multiplying its length by its width. The area of the semicircle is half the area of a full circle with the same radius. Finally, we add the two areas together to get the total area of the figure.
Let's assume the length of the rectangle is 10 units and the width is 5 units. The area of the rectangle is then 10 units * 5 units = 50 units^2. If the radius of the semicircle is 3 units, the area of the semicircle is half the area of a full circle with radius 3 units, which is 1/2 * 3.14 * 3^2 = 14.13 units^2 (rounded to the nearest tenths place).
Therefore, the total area of the figure is 50 units^2 + 14.13 units^2 = 64.13 units^2 (rounded to the nearest tenths place).

The approximate length of a side of the square field is 22 feet.
Given,
A square field has an area of 479 ft².
We need to find out what is the approximate length of a side of the field.
Give your answer to the nearest foot.
What is the area of a square?
It is given as :
Area = side²
Find the length of a side of a square.
Side = length of a side
Area = side²
We have,
Area = 479 ft²
479 = side²
Side = √479
Side = 21.886
Rounding to the nearest foot.
Side = 21.886 feet
0.886 can be round to 1 foot.
So,
Side = 22 feet.
Thus the approximate length of a side of the square field is 22 feet.

So all we really need to do for this one is
area=LW, L=W in squaer so 479=L^2, squaer root both sides, L=W=21.88=22 rounded
so it is C

2. The market price is 49 1/4, or $49.25
3 . It is selling par.(Par =$50,selling$49.25)
$50,000.00 ÷ 1,000 = $50.00
$49.25
Below par, because the par value is $50.00
$5.00 × 20 = $100.00
