Okay, so the formula of the area of a circle is \(\large r^2\pi\)
r = radius
OpenStudy (asad786):
whats the 2 for
OpenStudy (studygurl14):
That question said to find the area of a round glass table that has a diameter of 24
OpenStudy (asad786):
yes
OpenStudy (studygurl14):
Diameter is 2 times the radius, so to find the radius, you divide the diameter by 2.
24/2 = 12
radius = 12
