use the formula 2πr
- 106.76
- 300.96
- 2×3.14×(1/2)×39 = 122.46
- 78.5
the c bit I did the whole process cuz the diameter is given and for the d bit i thought what you were trying to say is 25 diameter.
hope it helps and don't forget to put the units wherever necessary.!!!!
Answer:
5x - 9
Step-by-step explanation:
2x -(-3x + 9)
2x + 3x - 9) DISTRIBUTE -1
5x - 9 COMBINE LIKE TERMS
The answer to this is 4.5359237 kilograms
Answer: c = 8 yards
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(45) = c/(8*sqrt(2))
c = 8*sqrt(2)*cos(45)
c = 8*sqrt(2)*(1/sqrt(2))
c = 8
----------------
Optionally, you can use the 45-45-90 triangle template which says that the length of the leg of this triangle is x and the hypotenuse is x*sqrt(2)
Since 8*sqrt(2) is the given hypotenuse, this must mean x*sqrt(2) = 8*sqrt(2) so x = 8
Answer:
-x is <u>19</u> units to the <u>right</u> of 0.
Step-by-step explanation:
If x is 19 units to the left of 0, then x=-19 and -x = 19.
Of course, 19 is 19 units to the right of 0.
