1. Area of a circle is pi(R)^2 , where R is the radius. So we can substitute:
22/7(16^2) = about 805 meters squared.
2. Let's find the area of the rectangle first.
A=LW
A= 18(10)
A= 180 cm squared.
Now the semi-Circle:
The radius of the circle is 9 (because 18/2 is 9). Now we plug in to the area formula:
22/7(9^2) = about 254 cm squared. But because that is the area of the whole circle, and we only need half of the circle, we divide that value by 2 to get:
127 cm squared for the semi-circle.
Now we add up the rectangle and semi-circle's areas:
180 + 127 = 307 cm squared as your answer.
I hope this Helps!
Answer:
C) m = -63 is your answer
Step-by-step explanation:
Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.
Multiply 3 to both sides
-21 = (m/3)
(-21)(3) = (m/3)(3)
m = (-21)(3)
Combine like terms. Simplify.
m = -21 * 3
m = -63
C) m = -63 is your answer
