Answer:
They used 3.14 for pi:


Step-by-step explanation:
is the volume of a sphere with radius r.
I think that is the diameter given in the picture.
The radius is half the diameter.
So the radius is 5 since the diameter is 10.
Plug in this gives you:

Answer:
1
Step-by-step explanation:
To find the slope, you must subtract the second y axis from the first y axis then the second x axis from the first x axis.
Problem: (5, 3) (-2, -4)
Solution: Step 1. - 4 - 3 = 7 (subtract the second y axis from the first y axis)
Step 2. - 2 - 5 = 7 (subtract the second x axis from the first x axis)
Answer: 7/7
Final Answer: 1
Mark me as brainliest!!
The solution step by step. 43 comes from adding all the given numbers together.
Answer:

Step-by-step explanation:
8^2+5^2=c^2
64+25=c^2
89=c^2
c=
<-- this is the length of the rectangle at the bottom
2^2+(
)^2=c^2
4+89=c^2
c=
<-- length of dotted line (diagonal)
