Question 168809: the question in my math book is 1/4 of out of a circle they are asking me to find the perimeter and the area the lenght of this 1/4 is 3cm the answer in the back of the book gives 10.71 for the perimeter and 7.065 for the area what are the steps that i need to take to come up with these two answers Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! 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 = + 2r
:
P = + 2(3)
:
P = 4.71 + 6
:
P = 10.71
:
:
Area: find the area of the circle and divide it by 4
:
A =
:
A =
:
A = 7.068 on my calc
