in a circle
Find the area of both circles (A = πr2) and subtract the area of the larger circle from that of the smaller circle inside it.
one fourth of circle
Fine the area of the jar then find the area of a quarter then divide the area of the jar by the area of the quarter and you get your answer.
A full circle is 360o, so a quarter, (one fourth) of a circle is 90o.
It is: 1/4*pi*144 = 36*pi square units
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
Half circle plus quarter circle is equal to three-fourths of a circle. Three-fourths of a circle plus one eighth of a circle is seven-eighths. You still need one more eighth to complete the circle.
1/4 of a circle is a 90 degree turn
There are 90 degrees
