Answer:
Step-by-step explanation:
SV = RV
2x+2 = 10
x = 4
r² = RV² + VZ² = 10²+7.5² = 156.25
UZ = √[r²- (QR/2)²] = √[156.25 - 10²] = √56.25 = 7.5
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:
B. 21.1 yd
Step-by-step explanation:
The perimeter of the figure is the sum of all its three sides.
Take note that the dotted line is not a side length of the figure.
The side lengths are 9 yd, 5 yd, and 7.1 yd.
Therefore, the perimeter of the figure = 9 + 5 + 7.1
Perimeter = 21.1 yd.
Also, take note of the unit of the perimeter. Unit of the perimeter would not be squared. Only area has a unit that is squarred.
