Answer:
The area of the circle is 50.24 mm
²
Step-by-step explanation:
To solve this exercise we need to use the area formula of a circle:
a = area
r = radius = 4mm
π = pi = 3.14
a = π * r²
a = 3.14 * (4mm
)²
a = 3.14 * 16mm
²
a = 50.24 mm
²
The area of the circle is 50.24 mm

X + y = 10
x - y = 2
add the equations together
2x = 12
x = 6
6 + y = 10
y = 3
Answer:
x= −1/3 y+5/3
Step-by-step explanation:
Let's solve for x.
y=−3x+5
Step 1: Flip the equation.
−3x+5=y
Step 2: Add -5 to both sides.
−3x+5+−5=y+−5
−3x=y−5
Step 3: Divide both sides by -3.
−3x
