Can someone please help me with this question the instructions are to use a calculator to find the perimeter (the solid lines and curves) of each figure. The perimeter of each semicircle can be found by using the equation 1/2 pi d (the place where I put the words pi has the pi symbol, and d is just a variable. Also use 3.14 as pi, and the top part is cut off a little bit, but it still counts as a full semi circle. Please help me.

Answer:

The continuous closed line that makes the boundary of a two-dimensional shape is known as the perimeter. It’s easy to work out the perimeter of a shape with straight edges, such as a square, because you simply add the lengths of each edge together. A different formula is required to work out the perimeter of a semi circle (a circle cut in half), because it consists of a curved edge as well as a straight edge. That formula is

Step-by-step explanation:

P = \frac{1}{2} πd + dP=

2

1

​

πd+d

where ​d​ is the diameter of the semi circle.

Apply the number pi (π) to the formula

P = \frac{1}{2} πd + dP=

2

1

​

πd+d

Pi is a circle's circumference divided by its diameter and is always the same value, 3.14.

Tell whether the difference between two negative integers is always, sometimes, or never positive. The difference between two negative integers is (blank) positive. Question 2 Explain your reasoning. 1) It’s always positive because the first integer is always greater. 2) It’s positive only if the first integer is greater. 3)It’s never positive because the first integer is never greater.

You now know a lot about all the angles formed from two straight lines that intersect. You know which angles are congruent and which angles are supplementary. Based on this information, you can find the angle measurements of all the angles even when you only know the measurement of one angle. In the figure below, angle 2 measures 145 degrees. What are the measurements of angles 1, 3 and 4? A angle 1 = 35 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees B angle 1 = 30 degrees, angle 3 = 30 degrees, angle 4 = 160 degrees C angle 1 = 35 degrees, angle 3 = 35 degrees, angle 4 = 145 degrees D angle 1 = 135 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees
