Answer:
The answer is "She is right since the center in the middle of the sphere is a fixed point".
Step-by-step explanation:
- We have a certain habit of the rules of equations in maths for points, coordinates, sections, edges, etc. Generally, developers mark points, researchers much more mark with the very first letter of an entity which we signify.
- This also shows divisions of a circle and a sphere as radius through a letter, r as radius, has high and usually as capital letters. If they denote radius, it should be put in the center or over the section we denote with such a small letter.
- They just need to put the letter near the point they are going to point out for marks, that's why it is correct.
Answer:
D dilation and reflection
Step-by-step explanation:
Rotation, reflection, and translation are "rigid" transformations, so will always result in congruent figures.
Dilation is a transformation that changes size, so will result in figures that are similar, but not congruent. Any rigid transformation performed with dilation will still result in a similar figure.
Hello!
The formula for finding area of a circle is: π · r²
Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.
The diameter is 13. 13 ÷ 2 = 6.5
r = 6.5
6.5² = 6.5 × 6.5 = 42.25
π = 3.14
Multiply 3.14 by 42.25 to get the area
3.14 × 42.25 = 132.665
<em>The area of the circle is 132.665 sq. units, which is the last option.</em>
I'm just guessing but try -7
You have to combine -5.8c+1.4c which = -4.4c
then
combine 4.2-3.1 which = 1.1
so the answer is
-4.4c+1.1 or you can switch the numbers around
