PLEASE HELP
Select ALL of the expressions that correctly calculate the perimeter of the shape.

1. 40 + 20π
2. + 20π
3. 120 + 20π
4. 300 + 100π
5. 10 + 10 + 10π + 10 + 10 + 10π

The expression . 40 + 20π and 10 + 10 + 10π + 10 + 10 + 10π gives the correct value of the perimeter is 102.8 .

We have to determine, the perimeter of the given shape in the question.

According to the question,

The squares have a side length of 10 and 1 square side is the radius of the half-circles.

There are two half-circles,

To find the circumference for one full circle:

Where radius = 10

The circumference of the circles is 62.8.

To find the perimeter of the exposed squares with side length 10.

There are 4 exposed sides, which equals one square.

Therefore, perimeter p is given as,

On adding  the perimeter of the circle and the square together:

Check all the statement which give perimeter of the shape,

Hence, The expression . 40 + 20π and 10 + 10 + 10π + 10 + 10 + 10π gives the correct value of the perimeter is 102.8 .

Step-by-step explanation:

The squares have a side length of 10 and 1 square side is the radius of the half-circles. Since there are two half-circles, find the circumference for one full circle:

Insert the radius:

Simplify pi:

Simplify multiplication:

The circumference of the circles is 62.8. Now find the perimeter of the exposed squares with side length 10. There are 4 exposed sides, which equals one square. Find the perimeter:

Add the perimeter of the circle and the square together:

Now see which of the options gives you the perimeter:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
