Is the answer 25? Thats what I got.
Hi
formula. for circumference of a circle is. : 2πR. if you have the radius.
As the diameter is twice the radius, then circumference is. diameter π
then : 18*π≈ 56.52
the mistake was to take the diameter as the radius.
Answer:
An object balances itself when a perpendicular line drawn through its Centre of Gravity (CG), passes through its base.
See the picture of a popular toy given below. The horse, the rider and the ball are all joined together as one single unit. This entire unit is balanced on the thin black rod shown. At which of the indicated positions, could the Centre of Gravity (CG) of the horse, rider and ball unit be?

Step-by-step explanation:
Plug in (1,8) to y ≤ 2x+2 and you get 8 ≤ 2+2 which is not true
Answer:
<u>x = 3</u>
Step-by-step explanation:
Equating the secants :
- 10 (10 + 5x + 2) = 9 (9 + 7x)
- 50x + 120 = 81 + 63x
- 63x - 50x = 120 - 81
- 13x = 39
- x = 3
