In step 2, V = 
show the error in volume work.
Solution:
Given data:
The steps shows it is sphere.
Radius of the sphere = 12.5
The value of π = 3.14
Volume of the sphere = 
Step 1:
Step 2:
Step 3:
Step 4:
V = 8177.08 cubic units
This is the correct solution.
But in the given options, in step 2, 12.5 is multiplied by 3.
That is not the correct step. You have to do 12.5 × 12.5 × 12.5.
Hence in step 2, V = show the error in volume work.
Add 4y to both sides of the equation:
x=4y-22
Now replace x in the equation:
(4y-22)-4y=-22
Distribute the negative sign:
-4y+22-4y=-22
Add common terms:
-8y+22=-22
Add 8y to both sides of the equation:
8y-22=22
Add 22 to both sides of the equation:
8y=44
Divide both sides by 8:
y=5.5
Answer:
<R=23°
Step-by-step explanation:
The sum of angles in a triangle is 180°
So, <R + <S + <T = 180°
<R+90°+67°=180°
<R+157°=180°
<R=23°
Answer: 35/3 or 11.6
Step-by-step explanation:
3x-7=28
Add 7 to each side
3x=35
Divide by 3
