Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.
I hope this helped!
The answer 19 because, 19+8=27, then 27 divided by 9 is equal to 3. If you need to know how I got 19 just let me know!
If you would like to solve the system of equations, you can do this using the following steps:
2x + 3y = 40
-2x + 2y = 20
____________
2x + 3y - 2x + 2y = 40 + 20
5y = 60 /5
y = 60/5
y = 12
<span>2x + 3y = 40
</span>2x + 3 * 12 = 40
2x + 36 = 40
2x = 40 - 36
2x = 4
x = 4/2
x = 2
(x, y) = (2, 12)
The correct result would be <span>d. x = 2, y = 12.</span>
<span>25.25 feet (25 feet 3 inches)</span>
