Step-by-step explanation:
To work out the Circumference of a circle, we must o the calculation
πd
π x d
If we fill in the information we know
π x 10.4
3.14 x 10.4 (to 2 d.p.)
↓
32.656 (units)
Answer: The required co-ordinates of point T are (13, -6).
Step-by-step explanation: given that S is the midpoint of the line segment RT, where the co-ordinates of point R are (-9, 4) and that of S are (2, -1).
We are to find the co-ordinates of point T.
We know that
the co-ordinates of the mid-point of a line segment with endpoints (a, b) and (c, d) are given by
![\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7Ba%2Bc%7D%7B2%7D%2C%5Cdfrac%7Bb%2Bd%7D%7B2%7D%5Cright%29.)
Let (h, k) be the co-ordinates of point T. Then, according to the given information, we have
![\left(\dfrac{-9+h}{2},\dfrac{4+k}{2}\right)=(2,-1)\\\\\\\Rightarrow \dfrac{-9+h}{2}=2\\\\\Rightarrow -9+h=4\\\\\Rightarrow h=4+9\\\\\Rightarrow h=13](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7B-9%2Bh%7D%7B2%7D%2C%5Cdfrac%7B4%2Bk%7D%7B2%7D%5Cright%29%3D%282%2C-1%29%5C%5C%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7B-9%2Bh%7D%7B2%7D%3D2%5C%5C%5C%5C%5CRightarrow%20-9%2Bh%3D4%5C%5C%5C%5C%5CRightarrow%20h%3D4%2B9%5C%5C%5C%5C%5CRightarrow%20h%3D13)
and
![\dfrac{4+k}{2}=-1\\\\\Rightarrow 4+k=-2\\\\\Rightarrow k=-2-4\\\\\Rightarrow k=-6.](https://tex.z-dn.net/?f=%5Cdfrac%7B4%2Bk%7D%7B2%7D%3D-1%5C%5C%5C%5C%5CRightarrow%204%2Bk%3D-2%5C%5C%5C%5C%5CRightarrow%20k%3D-2-4%5C%5C%5C%5C%5CRightarrow%20k%3D-6.)
Thus, the required co-ordinates of point T are (13, -6).

Answer:
12 square ft.
Step-by-step explanation:
A= l*w.
We already have the area so we have to work backwards.
144= l*w.
144/2= 12
let's plug it in.
144=12*12
