Problema Solution
If the area of a quarter circle is 46pie, what is its radius
Answer provided by our tutors
The area of the circle is calculated by the formula
A = r^2 * pi, where r is the radius
in our case
A/4 = 46*pi
that is
r^2 * pi / 4 = 46*pi
r^2 = 46*pi*4/pi
r^2 = 184
r = 13.56 approximately.
the radius is 13.56 approximately.
