The area of circle z is 64 ft2.
what is the value of r?
r = 4 ft
r = 8 ft
r = 16 ft
r = 32 ft

can 4.5 be rounded up to 4? nope.

For this case we have as data that the area of the circle is given by:

According to the following formula, we must find the radius of the circle:

Taking we have:

Finally, the radius of the circle is 4.5ft

4.5ft

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

answer is c

step-by-step explanation:

81/12=324/x

x=48
