A clock tower has a circular clock face with a circumference of 48π feet. What is the radius of the clock face ?
KatRina [158]

Answer:

r = 24 ft

Step-by-step explanation:

Circumference is given by

C = 2 * pi *r

We know that C  = 48 pi

48 pi = 2 * pi * r

Divide each side by pi

48 pi /pi= 2 * pi * r/pi

48 = 2 r

Divide each side by 2

48/2 = 2r/2

24 = r

In the figure below, GK is parallel to HJ<br> What is the measure of KMI?
My name is Ann [436]

Answer:

\huge\boxed{29 \textdegree}

Step-by-step explanation:

In order to find the measure of angle KMI, we need to note some angle relationships here.

GK and HJ are parallel lines cut by a transversal, meaning the angles formed by this transversal line will be the same along the parallel lines.

We know that the 29° angle is an alternate interior angle to KMI. This means their angle measures are the same.

Therefore, KMI is also 29°.

Hope this helped!
