Question 168809
find the perimeter and the area the length of this 1/4 is 3 cm 
:
Assume the radius is 3 cm
:
If you look a 1/4 circle you can see the perimeter will be:
1/4 * circumference + 2* radius
:
P = {{{(1/4)*2*pi*r}}} + 2r
:
P = {{{(1/4)*2*pi*3}}} + 2(3)
:
P = 4.71 + 6
:
P = 10.71
:
:
Area: find the area of the circle and divide it by 4
:
A = {{{(1/4)*pi*r^2}}}
:
A = {{{(1/4)*pi*3^2}}}
:
A = 7.068 on my calc
