Answer 1

The circumference (length of curve) of a circle is given by \(2 \pi r\), where \(r\) is the radius.

Answer 2

In this case, the radius is \(30 m\).

Answer 3

\({XPY}\) is \(\frac34\) of the circle.

Answer 4

So what does that mean? :l

Answer 5

The circumference (length of curve) of the whole circle is \(2\pi(30)\) which is \(60\pi\)

Answer 6

The \(\dfrac34\) of it would be \(\left(\dfrac34\right)60\pi\) which would be \(45\pi\).

Answer 7

Oh I suspected it was that one! Thank you very much
