Question 314568
I have a math problem where pi=22/7 and i have to find the area of a circle using pi with a diameter of 3 1/2
.
{{{ A = (pi)r^2 }}}
Of course, radius(r) is simply half the diameter so
r = (1/2)(3.5) = 1.75 or 1 3/4 or 7/4
.
Plug the given info into:
{{{ A = (pi)r^2 }}}
{{{ A = (22/7)(7/4)^2 }}}
{{{ A = (22/7)(49/16) }}}
{{{ A = (22)(7/16) }}}
{{{ A = (11)(7/8) }}}
{{{ A = 77/8 }}} square units
