Margarita [4]

Answer:

<h2> A = 24.5 square units</h2>

Step-by-step explanation:

$J(-3,\,4)\ \ \implies\ y_J=4\\\\K(4,\,4)\ \ \implies\ y_K=4\\\\y_K=y_J\ \ \implies\ JK\parallel X{-}axis\ \implies\ H=|y_L-y_K|\quad\ \{for\ JK=base\}\\\\H=|-3-4|=|-7|=7\\\\\\ JK\parallel X{-}axis\ \implies\ B=JK=|x_J-x_K|=|-3-4|=7\\\\\\A=\frac12BH\\\\A=\frac12\cdot7\cdot7=24.5$

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
