Answer:
16П or approximately 50.3)
Step-by-step explanation:
The area of a circle is equal to П*r²
Since the circle is inside a rectangle with side that is equal to 8, we know that d = 8
2r = d
r = 8/2
r = 4
A = П*r²
A = П*16
А = 16П ( or 16*3.141592653589793238... = 50.26548... ≈ 50.3)

do what u will with that info I'm bad at wording things
Answer:
The answer to your question is y = 2x + 11
Step-by-step explanation:
Data
Original line y = -(1/2)x + 5
Point (-4, 3)
Process
1.- Get the slope of the new line
- Slope of the original line = -1/2
If the lines are perpendicular, the slopes must be reciprocal
-1/2 reciprocal = 2
2.- Get the equation of the new line
y - y1 = m(x - x1)
y - 3 = 2(x + 4)
- Simplification
y - 3 = 2x + 8
- Solve for y
y = 2x + 8 + 3
y = 2x + 11
When changing fractions into decimals the whole number goes before the period and the fraction goes after.The denominator of the fraction will tell you whether or not you need to put any zeros before the numerator. If the denominator is 10 zeros are not needed.The end result is 7.2 and can be read as seven tenths.
