Circumference is the diameter of the circle multiplied by PI

To find the diameter when the circumference is known, divide the circumference by PI.

30 / PI = 30/3.14 = 9.97 Round to 10m

Answer:

10 m

Step-by-step explanation:

The circumference of a circle is given by

C = pi*d

Substituting what we know

30 = pi*d

Divide each side by pi

30/pi = d

Pi is approximately 3.14

30/3.14 = d

9.55 =d

The closest number is 10

  • MP of AC = MP of BD

\huge \rightarrow \frac{x + 1}{2},\frac{y+ 3}{2} =  \frac{5 + 1}{2},\frac{3 - 2}{2}  \\

\huge \rightarrow \: x = 5 \:  \\  \huge \rightarrow \: y =  - 2
