4L + πr

Step-by-step explanation:

Since her yard is a square and half a circle, and she wants to fence the whole distance around the square and the half circle, then she needs to know the perimeter of a square and semicircle.

The perimeter of a square which is the distance around the square is given by 4L where L is the side length.

The perimeter of a circle, which is the circumference of a circle is 2πr, where r is the radius of the circle Therefore, half a circle would be 2πr/2 = πr

(b) The diameter of the semi-circle is 17 meters.

(c)  To enclose the entire yard and keep Sprinkles from running away, the fencing needs to be 8.5π + 68 meters.

A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.

Given that Laura’s yard is in the shape of a square and a semi-circle.

The side of the square is 17 meters.

(b). To find the diameter of the semi-circle:

The diameter of the semi-circle = side length of a square.

The diameter of the semi-circle is 17 meters.

(c). To enclose the entire yard and keep Sprinkles from running away,

the total perimeter = the perimeter of the square + the perimeter of the semi-circle

= 4(17) + π(8.5)

= 8.5π + 68 meters

Therefore, the perimeter is 8.5π + 68 meters.

Answer:

The surface area is 86.9

Step-by-step explanation:

First find the area of the base:

5.3 • 2 = 10.6

The area opposite of the base are equal:

10.6 + 10.6 = 21.2

Find the area of the front rectangle:

5.3 • 4.5 = 23.85

The area opposite of the rectangle are equal:

23.85 + 23.85 = 47.7

Find the area of the rectangle on the sides:

4.5 • 2 = 9

The area opposite of the shape on the side are equal:

9 + 9 = 18

Add up the areas:

21.2 + 47.7 + 18 = 86.9

Answer: First of all, add up the expressions with the same variables and the numbers.

Step-by-step explanation:

Answer:

none of the above

Step-by-step explanation:

The equivalent expression which is equal to - 9.7 × - 0.8 × - 7.8 × 3.8 is,

A) 9.7 × - 0.8 × - 7.8 × - 3.8

Given that,

The expression is,

- 9.7 × - 0.8 × - 7.8 × 3.8

Now, we used the concept of negative signs of numbers to find equivalent expressions,

Here, the expression is,

- 9.7 × - 0.8 × - 7.8 × 3.8

Since there are three negative signs.

So, the solution is always found with a negative sign.

As we know,

[tex]- \times - \times - = -[/tex]

So, by giving options,

The expression represents in option A has the same numbers with three negative signs.

That is, 9.7 × - 0.8 × - 7.8 × - 3.8

Therefore, the equivalent expression is,
