X=6 because 3X6=18 so x=6
Answer:
The answer to your question is 9923 cm²
Step-by-step explanation:
Data
radius = 30.8 cm
height = 20.5 cm
Surface area = ?
Process
1.- Write the formula to calculate the surface area of a cylinder
SA = 2πr² + 2πrh
2.- Substitution
π = 3.14
SA = 2(3.14)(30.8)² + 2(3.14)(30.8)(20.5)
3.- Simplification
SA = 5957.459 + 3965.192
4.- Result
SA = 9922.65 cm² or SA = 9923 cm²
Answer:
No
Step-by-step explanation:
To determine if the 3 sides form a right triangle.
Use the converse theorem of Pythagoras.
If the square of the longest side is equal to the sum of the squares of the other two sides then the triangle is right,
longest side = 14 and 14 ² = 196
9² + 12² = 81 + 144 = 225
Since 196 ≠ 225 the triangle is not right
Answer:
The quotient of -27/9 is -3 hope this helps <3
Step-by-step explanation:
