Answer:
The area of the circle is 379.94 mm²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 11 mm
π = 3.14
a = π * r²
we replace with the known values
a = 3.14 * (11 mm)²
a = 3.14 * 121 mm²
a = 379.94 mm²
Round to the nearest tenth
a = 379.94 mm² = 379.9 mm²
The area of the circle is 379.9 mm²

Answer:
multiply the first equation by -2, then add them
Step-by-step explanation:
7x+4y=-4 *-2 7x+4y=-4 *-2 = -14x-8y=8
5x+8y=28
-14x-8y=8 x=-4, y=6
-9x=36
x=-4
7(-4)+4y=-4
-28+4y=-4
4y=24
y=6
