Answer:
.79 mm^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 (1) ^2
A = 3.14
Now we have 1/4 of the circle
The area is 1/4 of the full area
1/4 *3.14
.785
Rounding to the nearest hundredth
.79 mm^2
A + m = 54, m = a + 4 and, a + m = 54, - a + m = 4,
Combine the equations: 2m = 58
Now solve: 2m = 58, 2m/2 = 58/2, m = 29, therefore a = 24
