The Diagram Shows A Track Composed Of A Rectangle With A Semicircle On Each End. The Area Of The Rectangle

Answers

Answer 1

Answer:

The perimeter of the track is the two circumferences of the semicircles (when combined, they form one circle, so we can just find the circumference of the circle) added to the lengths of the rectangle (160 meters).

To find the circumference of the circle, we need to know the diameter.

Circumference of a circle: dπ or 2rπ, where d represents diameter and r represents radius

The diameter of the circle happens to be the same as the width of the rectangle. We know that the area of a rectangle is found by multiplying its length by its width. We know that the area is 14400 and that its length is 160.

Width: area divided by length

14400160=90

The diameter of the circle and the width of the rectangle is 90 meters.

Circumference:

90⋅π=90π→ If you are using an approximation such as 3.14 for π, multiply that by 90

Add 160⋅2 to the circumference since the lengths of the rectangle are also part of the perimeter.

160⋅2=320

90π+320

​The picture shows the front view of a house.





What is the area of the front of the house in square feet?


square feet

Answers

600 square feet

Using the formulas given:

1/2(24)(10) = 120 sq ft for the triangle part

and

(20)(24) = 480 sq ft for the rectangle part

120 + 480 = 600 square feet
The answer is 600 square feet

Answer:

M1= 35°   M2=30°

Step-by-step explanation:

At the point where the two triangle meet, the north angle is 115°, so the south one will be 115°, because they're alternate angles. This means that to get the other two angles left, you must subtract the two angles that weren't in the triangles on that point = 360° - (115 x 2) = 130°. 130° is the total of the two angles on the point in the two triangles. Then you just subtract the two angles you have for each triangle from 180° to get the last two angles
