Explanation:

Find the measure of arc MCN

The measure of a full circle is \(360^\circ\). The major arc \(\widehat{CAN}\) has a measure of \(226^\circ\). The remaining arc \(\widehat{MCN}\) completes the circle:

$$ m\widehat{MCN} = 360^\circ - m\widehat{CAN} = 360^\circ - 226^\circ = 134^\circ $$

Find the circumference of circle E

The diameter of circle \(E\) is \(DF = 30\). The formula for the circumference \(C\) using diameter \(d\) is:

$$ C = \pi d = 30\pi \approx 94.25 $$

Find the measure of arc MDW

The major arc \(\widehat{DOW}\) has a measure of \(294^\circ\). The remaining arc \(\widehat{MDW}\) completes the circle:

$$ m\widehat{MDW} = 360^\circ - m\widehat{DOW} = 360^\circ - 294^\circ = 66^\circ $$

Find the circumference of circle N

The radius of circle \(N\) is \(NO = 24\). The formula for the circumference \(C\) using radius \(r\) is:

$$ C = 2\pi r = 2\pi(24) = 48\pi \approx 150.80 $$

Find the circumference of circle U

The radius of circle \(U\) is \(UQ = 13\). The formula for the circumference \(C\) is:

$$ C = 2\pi r = 2\pi(13) = 26\pi \approx 81.68 $$

Find the length of OT

The segment \(ON\) is a radius of circle \(O\), so \(ON = 43\). Since \(OT\) is also a radius of the same circle \(O\), its length must be equal to \(ON\):

$$ OT = ON = 43 $$

Find the circumference of circle R

The diameter of circle \(R\) is \(IS = 17\). The formula for the circumference \(C\) is:

$$ C = \pi d = 17\pi \approx 53.41 $$

Find the length of UV

The segment \(TV\) is a diameter of circle \(U\) with length \(TV = 32\). The segment \(UV\) is a radius of circle \(U\). The radius is half of the diameter:

$$ UV = \frac{TV}{2} = \frac{32}{2} = 16 $$
