Su = 15 !!!!!!!!!!!!!! chile i hope Im not wrong lol
You would set up the proportion 25/X= 32/100.
25*100 is 2500, 32*x is 32x
2500 = 32x
/32 /32 dividing by 32 on both sides
78.125 = x

Answer:</h3>
- 21π(10)^2 – 21π(6)^2
- 2,100π – 756π
<h3>
Step-by-step explanation:</h3>
The volume of metal is the difference of the overall volume of the cylinder and the volume of the hole in it. The formula for the volume of a cylinder is ...
... V = π·r^2·h . . . . . radius r and height h
For the overall dimensions, the radius is half the diameter, so is 10 mm. The hole is said to have a radius of 6 mm. The overall "height" is 21 mm, so the volume in mm³ will be ...
... V_overall -V_hole = π(10)^2(21) -π(6)^2(21)
... = 21π·10^2 -21π·6^2 . . . . . . . matches the first selection
... = 2100π -756π . . . . . . . . . . . matches the third selection
... = 1344π . . . . . . . . . . . . . . . . doesnt' match any selection
Answer:
x = 21
Step-by-step explanation:
given : angle a = 75
we need to find the value of x.
To find the value of x.
we know that it is a straight angle so the sum of angles on a line will be 180
3x + 2x + a = 180
5x + 75 = 180
5x = 180 - 75
5x = 105
x = 105/5
x = 21
